Uri Alon was long puzzled by a textbook statistic: Longevity, the thinking went, was about 20 percent in our genes. “That makes you think what’s the rest of the 80 percent: Is it the lifestyle? Why should we study genes for lifespan if it’s not that important? It kind of bothered me,” said Alon, a physicist turned systems biologist at the Weizmann Institute of Science in Israel. Alon us

The Artemis 2 astronauts might be the first humans to survey certain areas of the moon's far side, and they're chronicling their historic journey in detail.

By Joey Roulette HOUSTON, Texas April 6 (Reuters) - The four astronauts of NASA's Artemis II mission reached the furthest point that any human has been from Earth on Monday, cruising along a path in

The Orion's four crew members have surpassed the mark previously set by Apollo 13 in 1970.

During the seven-hour trip around the moon, the Orion's four crew members will surpass the record for the farthest distance from Earth traveled by humans.

The four astronauts of NASA's Artemis 2 mission have arrived at the moon. They entered the lunar sphere of influence early Monday morning (April 6).

NASA's Artemis 2 astronauts will make a historic moon flyby today (April 6). Here's how it will happen, hour by hour.

The distance Orion will travel during the Artemis II moon flyby will let the crew see the entire lunar disk, including features Apollo astronauts didn’t observe.

With the moon looming ever larger, the Artemis II astronauts raced to set a new distance record Monday from Earth on a lunar fly-around promising magnificent views of the far side never seen before by eye. The six-hour flyby is the highlight of NASA's first return to the moon since the Apollo era with three Americans and one Canadian — a step toward landing boot prints near the moon's south pole in just two years. A prize — and bragging rights — awaits Artemis II.

The crew’s Orion capsule entered what’s known as the lunar sphere of influence at around 12:41 a.m. ET Monday, crossing into the region of space where the moon’s gravitational pull is stronger than the pull of Earth’s.

The four Artemis 2 astronauts had a chance to observe the moon this weekend, and to say they were thrilled may be an understatement of cosmic proportions.

The four Artemis 2 astronauts will see a solar eclipse from beyond the moon's far side on Monday evening (April 6), and they'll use the opportunity to make some science observations.

The NASA astronauts also sent down Easter messages Sunday while gearing up for a historic pass behind the moon Monday.

This offers us a glimpse of the discovery surge scientists expect to occur once full operations begin.

The on-again, off-again lunar loo allows astronauts to "go" at the moon like no one's gone before.

The four-member crew successfully completed a "translunar injection burn" on Thursday, sending them out of Earth's orbit and toward the moon.

Plans are in place for the crew of Artemis 2 to try to replicate one of the most famous images ever taken from space — Apollo 8's shot of Earth rising over the moon's horizon.

The crew of NASA's Artemis II mission captured a new image of the far side of the moon, which the agency released Sunday.

When early hints of a connection between autism and Alzheimer’s began to appear in the medical literature a few years ago, they struck him as implausible - one a condition of early brain development, the other driving decline in old age. But the signals kept accumulating, and over time, his skepticism gave way to a new line of inquiry that could

NASA astronaut Victor Glover delivered an impromptu Easter message as his Artemis 2 Orion capsule sped toward the moon on Saturday (April 4).

Astronomers discovered dozens of stellar streams in the Milky Way using Gaia data, offering new clues about galaxy formation and dark matter.

The Artemis II astronauts are already the champions of a fresh new era of lunar exploration. Launched last week on humanity’s first trip to the moon since 1972, the three Americans and one Canadian are chasing after Apollo 13’s maximum range from Earth. A total solar eclipse also awaits them as the moon blocks the sun, exposing snippets of shimmering corona.

The golden poison dart frog may be tiny, but it has earned a formidable reputation in the animal kingdom. Native to a small region of rainforest in western Colombia, this brightly colored amphibian is widely regarded as one of the most toxic animals on Earth! Its vivid yellow or orange coloring offers a warning to

The astronauts on NASA's Artemis 2 moon mission reported a burning smell from their Orion spacecraft toilet overnight, but Mission Control isn't overly concerned. They are over halfway to the moon today.

In an interview with NBC News from space, the crew of NASA's Artemis II moon mission described seeing the moon from a new angle, feelings of awe and humility, and taking care of their human needs.

On Episode 204 of This Week In Space, Rod Pyle and Tariq Malik bring it to you from Houston, as the Artemis 2 mission continues.

The radiated tortoise in Madagascar faces extinction due to poaching and illegal trade despite its long lifespan and unique beauty.

As the Artemis II mission makes its way toward the moon, photos taken by the crew have shifted from highlighting Earth to refocusing on the moon.
