Easter Science: 6 Facts About Jesus

He may be the most famous man who ever lived, but surprisingly little is known about his life.

This Sunday (March 31), more than 2 billion Christians will celebrate Jesus Christ's resurrection from the dead. While there is no scientific way to know whether that supernatural event at the heart of Christianity actually happened, historians have established some facts about his life.

From his birth to his execution by the Romans, here are six facts about the historical Jesus.

1. His birth … in a manger?

Most historians believe Jesus was a real man. To test the veracity of biblical claims, historians typically compare Christian accounts of Jesus' life with historical ones recorded by Romans and Jews, most notably the historians Flavius Josephus and Cornelius Tacitus.

And though a manger may or may not have figured prominently in the birth, scholars do agree that Jesus was born between 2 B.C. and 7 B.C. as part of the peasant class in a small village called Nazareth in Galilee. Historians also back the claim that Joseph, Jesus' father, was a carpenter, meaning Jesus would have gone into the family profession as well.

2. A mystical baptism

One of the pivotal moments in the New Testament is Jesus' baptism in the wilderness by a radical mystic named John the Baptist. Most historians believe this event actually occurred, and that Jesus experienced some sort of vision that led him to begin preaching. In the New Testament, Mark 1:10 (The New American Bible, Revised Edition) describes Jesus seeing "the heavens being torn open and the Spirit, like a dove, descending upon him." Jesus is then tempted by Satan in the wilderness for 40 days, the passage continues.

The Jewish historian Josephus mentions the mystical activities of John the Baptist, as well as his execution by King Herod. [History's 10 Most Overlooked Mysteries]

3. Reformer

After his vision, Jesus began to preach that the Earth could be changed into a "Kingdom of God." Jesus' message of reform was deeply rooted in the Jewish tradition, and he likely never viewed himself as creating a new religion per se — just reforming the one he was born into, scholars say.

4. A wise teacher

Josephus not only mentions Jesus, in one passage he also describes him as a wise man and a teacher. (The passage is controversial because many historians believe a Christian author later added in phrases such as "He was the messiah" to the text, leading a few scholars to doubt the authenticity of the passage as a whole). Most historians agree, however, that Jesus was viewed as a teacher and healer in Galilee and Judea.

5. Timing of Jesus' crucifixion

Several sources mention Jesus' crucifixion at the hands of Pontius Pilate, the Roman prefect. Christian Gospels say the skies darkened for hours after the crucifixion, which historians viewed either as a miracle or a portent of dark times to come. Using astronomy, later historians have used this mention to pinpoint the death of Christ. Some tie the crucifixion to a one-minute 59-second total solar eclipse that occurred in 29 C.E., whereas others say a second total eclipse, blocking the sun for four minutes and six seconds, in 33 C.E. marked Jesus' death. (C.E. stands for Common Era or Christian Era, and is an alternative name for anno Domini, or A.D.)

Death by crucifixion was one of the goriest ends the Romans meted out, and it was typically reserved for slaves and those seen to be challenging Roman authority.

6. Historical relics

The historical veracity of various physical relics, such as the crucifixion nails and crown of thorns Jesus wore on the cross, have decidedly less historical or scientific backing. Most scientific studies suggest that these relics originated long after Jesus died. But the most famous relic of Jesus, the shroud of Turin, may be on more solid footing: Whereas some parts of the shroud date to A.D. 1260, other analyses have suggested that the shroud is about as old as Jesus.

Another more recent finding, a scrap of papyrus from the early Christian era referring to Jesus' wife was unveiled last year, to much skepticism. Since then, evidence has come out to suggest the so-called Gospel of Jesus' Wife is a forgery, though the jury may still be out on that relic.

Pagan Roots? 5 Surprising Facts About Christmas

When you gather around the Christmas tree or stuff goodies into a stocking, you're taking part in traditions that stretch back thousands of years — long before Christianity entered the mix.

Pagan, or non-Christian, traditions show up in this beloved winter holiday, a consequence of early church leaders melding Jesus' nativity celebration with pre-existing midwinter festivals. Since then, Christmas traditions have warped over time, arriving at their current state a little more than a century ago.

Read on for some of the surprising origins of Christmas cheer, and find out why Christmas was once banned in New England.

1. Early Christians had a soft spot for pagans

It's a mistake to say that our modern Christmas traditions come directly from pre-Christian paganism, said Ronald Hutton, a historian at Bristol University in the United Kingdom. However, he said, you'd be equally wrong to believe that Christmas is a modern phenomenon. As Christians spread their religion into Europe in the first centuries A.D., they ran into people living by a variety of local and regional religious creeds.

Christian missionaries lumped all of these people together under the umbrella term "pagan," said Philip Shaw, who researches early Germanic languages and Old English at Leicester University in the U.K. The term is related to the Latin word meaning "field," Shaw told LiveScience. The lingual link makes sense, he said, because early European Christianity was an urban phenomenon, while paganism persisted longer in rustic areas.

Early Christians wanted to convert pagans, Shaw said, but they were also fascinated by their traditions.

"Christians of that period are quite interested in paganism," he said. "It's obviously something they think is a bad thing, but it's also something they think is worth remembering. It's what their ancestors did." [In Photos: Early Christian Rome]

Perhaps that's why pagan traditions remained even as Christianity took hold. The Christmas tree is a 17th-century German invention, University of Bristol's Hutton told LiveScience, but it clearly derives from the pagan practice of bringing greenery indoors to decorate in midwinter. The modern Santa Claus is a direct descendent of England's Father Christmas, who was not originally a gift-giver. However, Father Christmas and his other European variations are modern incarnations of old pagan ideas about spirits who traveled the sky in midwinter, Hutton said.

2. We all want that warm Christmas glow

But why this fixation on partying in midwinter, anyway? According to historians, it's a natural time for a feast. In an agricultural society, the harvest work is done for the year, and there's nothing left to be done in the fields.

"It's a time when you have some time to devote to your religious life," said Shaw. "But also it's a period when, frankly, everyone needs cheering up."

The dark days that culminate with the shortest day of the year ­— the winter solstice — could be lightened with feasts and decorations, Hutton said.

"If you happen to live in a region in which midwinter brings striking darkness and cold and hunger, then the urge to have a celebration at the very heart of it to avoid going mad or falling into deep depression is very, very strong," he said.

Stephen Nissenbaum, author of the Pulitzer Prize finalist "The Battle for Christmas" (Vintage, 1997), agreed.

"Even now when solstice means not all that much because you can get rid of the darkness with the flick of an electric light switch, even now, it's a very powerful season," he told LIveScience.

3. The Church was slow to embrace Christmas

Despite the spread of Christianity, midwinter festivals did not become Christmas for hundreds of years. The Bible gives no reference to when Jesus was born, which wasn't a problem for early Christians, Nissenbaum said.

"It never occurred to them that they needed to celebrate his birthday," he said.

With no Biblical directive to do so and no mention in the Gospels of the correct date, it wasn't until the fourth century that church leaders in Rome embraced the holiday. At this time, Nissenbaum said, many people had turned to a belief the Church found heretical: That Jesus had never existed as a man, but as a sort of spiritual entity.

"If you want to show that Jesus was a real human being just like every other human being, not just somebody who appeared like a hologram, then what better way to think of him being born in a normal, humble human way than to celebrate his birth?" Nissenbaum said. [Religious Mysteries: 8 Alleged Relics of Jesus]

Midwinter festivals, with their pagan roots, were already widely celebrated, Nissenbaum said. And the date had a pleasing philosophical fit with festivals celebrating the lengthening days after the winter solstice (which fell on Dec. 21 this year). "O, how wonderfully acted Providence that on that day on which that Sun was born … Christ should be born," one Cyprian text read.

4. The Puritans hated the holiday

But if the Catholic Church gradually came to embrace Christmas, the Protestant Reformation gave the holiday a good knock on the chin. In the 16th century, Christmas became a casualty of this church schism, with reformist-minded Protestants considering it little better than paganism, Nissenbaum said. This likely had something to do with the "raucous, rowdy and sometimes bawdy fashion" in which Christmas was celebrated, he added.

In England under Oliver Cromwell, Christmas and other saints' days were banned, and in New England it was illegal to celebrate Christmas for about 25 years in the 1600s, Nissenbaum said. Forget people saying, "Happy holidays" instead of "Merry Christmas," he said.

"If you want to look at a real 'War on Christmas,' you've got to look at the Puritans," he said. "They banned it!"

5. Gifts are a new (and surprisingly controversial) tradition

While gift-giving may seem inextricably tied to Christmas, it used to be that people looked forward to opening presents on New Year's Day.

"They were a blessing for people to make them feel good as the year ends," Hutton said. It wasn't until the Victorian era of the 1800s that gift-giving shifted to Christmas. According to the Royal Collection, Queen Victoria's children got Christmas Eve gifts in 1850, including a sword and armor. In 1841, Victoria gave her husband, Prince Albert, a miniature portrait of her as a 7-year-old; in 1859, she gave him a book of poetry by Alfred, Lord Tennyson.

All of this gift-giving, along with the secular embrace of Christmas, now has some religious groups steamed, Nissenbaum said. The consumerism of Christmas shopping seems, to some, to contradict the religious goal of celebrating Jesus Christ's birth. In some ways, Nissenbaum said, excessive spending is the modern equivalent of the revelry and drunkenness that made the Puritans frown.

"There's always been a push and pull, and it's taken different forms," he said. "It might have been alcohol then, and now it's these glittering toys."

8 Surprising Space Shuttle Facts (SPACE.com)

After 30 years of service, NASA's fleet of three space shuttles is standing down for good.

The final shuttle mission planned, the STS-135 launch of Atlantis, is scheduled for July 8. After that, the orbiters will be headed to museums to live out their lives on public display.

As we say goodbye to the iconic reusable space planes, here are eight surprising shuttle facts to keep in mind:

1. Top speed

While in orbit, the space shuttle travels around Earth at a speed of about 17,500 miles (28,000 kilometers) per hour. At this speed, the crew can see a sunrise or sunset every 45 minutes. [10 Amazing Space Shuttle Photos ]

2. Well traveled

The combined mileage of all five orbiters is 513.7 million miles (826.7 million km), or 1.3 times the distance between Earth and Jupiter. Each orbiter, except for Challenger, traveled farther than the distance between Earth and the sun.  

3. Presidential attention

Only one president has been on hand to witness a space shuttle launch. President Bill Clinton, along with his wife Hillary Clinton, watched Mercury astronaut John Glenn's return to space on the STS-95 flight on Oct. 29, 1998 from the Kennedy Space Center in Florida.

President Obama had planned to watch the shuttle Endeavour lift off on its final mission STS-134, on April 29, 2011, but that launch was delayed. The President and his family did visit the spaceport anyway.

4. Space science

The space shuttle isn't just a mode of transport: It's a laboratory, too. There have been 22 Spacelab missions, or missions where science, astronomy, and physics have been studied inside a special module carried on the space shuttle. [9 Weird Things Flown on NASA's Shuttles ]

Spacelab, a reusable laboratory built for use on space shuttle flights, allowed scientists to perform experiments in microgravity . Starting in 1983's Challenger missions, animals became a prime component of space science. On the STS-7 mission, the social activities of ant colonies in zero gravity were examined, and during STS-8, six rats were flown in the Animal Enclosure module to study animal behavior in space.

5. Taking the heat

The space shuttle's Thermal Protection System, or heat shield, contains more than 30,000 tiles that are constructed essentially of sand.

All of the tiles are thoroughly inspected before liftoff – they are a crucial tool that allows the space shuttle to endure the intense heat endured when the shuttle re-enters Earth's atmosphere to land. After the tiles are heated to peak temperature, the tiles can cool fast enough to be held in your hand only a minute later.

6. Packing on the pounds

The heaviest space shuttle orbiter, Columbia, weighed 178,000 pounds (80,700 kg), roughly the weight of 13 African Elephants.

Columbia, the first space shuttle to fly, weighed the most because NASA was still searching for lighter materials to use, and integrated some of these into the later orbiters.

7. Official monikers

The space shuttle program is officially known as the Space Transportation System (STS), and so each shuttle mission is designated with the prefix "STS."

Initially, the missions were given sequential numbers indicating their order of launch, from STS-1 through STS-9. However, because the then-NASA administrator James Beggs suffered from triskaidekaphobia  (the fear of the number 13) and wanted to avoid associations with the unlucky Apollo 13 mission, the agency drew up a new  numbering system for space shuttle missions, according to NASA history accounts by several astronauts at time.

What would have been STS-11 was named STS-41-B, STS-12 became STS-41-C, and STS-13 was STS-41-D. The first number was the last digit in the fiscal year (1984), the second number indicated the launch site (1 for Kennedy Space Center, and 6 for Vandenberg Air Force Base), and the letter indicated the sequence (A was the first launch of the year, and so on).

After the 1986 Challenger shuttle disaster, when that orbiter and its STS-51-L mission crew were lost, the agency resumed the sequential numbering system, starting with STS-26.

8. Tweeting from space

On May 11, 2009, astronaut Michael J. Massimino, a crewmember of the space shuttle Atlantis’ STS-125 mission, became the first person to use the microblogging site Twitter in space.

Writing as @Astro_Mike, he tweeted "From orbit: Launch was awesome!! I am feeling great, working hard, & enjoying the magnificent views, the adventure of a lifetime has begun!"

Since then, many astronauts from NASA and other space agencies have posted Twitter messages from space. One, NASA spaceflyer Doug Wheelock, won a Twitter Shorty Award earlier this year for the posts and photos he shared from space using the website during his months-long stay aboard the International Space Station.

For NASA's final space shuttle mission, all four of Atlantis' crewmembers have Twitter alias. They are: commander Chris Ferguson (@Astro_Ferg), pilot Doug Hurley (@Astro_Doug), mission specialist Sandy Magnus (@Astro_Sandy) and mission specialist Rex Walheim (@Astro_Rex).

Atlantis's final mission is STS-135 and will fly a 12-day mission to deliver vital supplies and spare parts to the International Space Station. NASA is retiring all three of its shuttles after 30 years to make way for a new program aimed at sending astronauts on deep space missions to an asteroid and other targets.
