A three-man one-woman crew blasted off on a voyage to the moon Wednesday, riding atop the world’s most powerful operational rocket as it roared away on a trail-blazing flight to help pave the way for upcoming lunar landings and an American moon base.
Using the James Webb Space Telescope, astronomers have investigated the star-forming region W51, resulting in stunning new images.
NASA's Artemis 2 has launched on a history-making journey around the moon and back, and the moment was captured from space.

The launch of NASA's historic Artemis 2 mission looks incredible in these stunning launch photos.
Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the rotational spins of galaxies would force them to simply fly apart. But now, scientists have found a string of galaxies that seem to be missing their dark matter entirely. The latest in this string, known as NGC 1052-DF9, is described in a new paper, available in pre-print on arXiv, by Michael Keim, Pieter van Dokkum and their team from Yale. It lends credence to a radical theory of galaxy formation known as the “Bullet Dwarf” collision scenario, which has been a controversial idea for the last decade.
"we have a beautiful moon rise, we're headed right at it."
Artemis 2 is gearing up for a critical engine burn this evening (April 2), which will send the mission's four astronauts on a looping journey around the moon.

Artemis II launched on 2 April at 00:35 CEST, (18:35 local time on 1 April), sending astronauts around the Moon for the first time in over 50 years. At the heart of the mission is ESA's European Service Module, which powers, propels and sustains the Orion spacecraft and its crew on their journey around the Moon and safely back to Earth.
It wasn't their No. 1 problem, but it was a problem for going number one.
That's one small sip of Manischewitz…
At 00:35 CEST today (18:35 local time on 1 April), NASA's Space Launch System rocket lifted off from the Kennedy Space Center in Florida, carrying four astronauts aboard the Orion spacecraft on Artemis II. At the heart of the mission is ESA's European Service Module, which powers, propels and sustains the Orion spacecraft and its crew on their journey around the Moon and safely back to Earth.
NASA launched its Artemis 2 mission today (April 1), sending astronauts toward the moon for the first time in more than 50 years.
For some time, astronomers have theorized that there is a connection between planetary mass and rotation. In the Solar System, Jupiter and Saturn both rotate rapidly, completing a rotation in roughly ten hours, while accounting for a significant fraction of the Solar System's rotational energy. Using the W.M. Keck Observatory on Maunakea, Hawai'i, a team of astronomers tested this predicted relationship by studying 32 gas giants and brown dwarfs in distant star systems - 6 giant planets larger than Jupiter and 25 brown dwarf companions
NASA’s Artemis 2 mission has departed Earth, as humans return to cis-lunar space after more than 50 years.
It started with an Instagram message, and ended on the silver screen.
Venus and Jupiter dominate April's evening sky, while Mercury, Mars and Saturn linger in the dawn — here's how and when to spot them all.
The universe is home to an astonishing variety of galaxies, from small dwarf galaxies to colossal spirals. Among the known galaxies, Alcyoneus currently holds the distinction of being the largest known galaxy by physical size.
Here's what's on the experiment roster for the Artemis 2 moon mission.
Artificial Intelligence (AI) and Machine Learning (ML) are making a growing contribution to astronomy. As powerful telescopes and large automated surveys become more commonplace, the vast quantities of data they generate demand equally powerful diagnostic tools. The Vera Rubin Observatory and its enormous data-generating capacity drive the point home. The observatory's Legacy Survey of Time and Space generates up to 20 terabytes of data each night, and that data is processed at a dedicated facility.
