Engineers and scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, completed tests this month on a second early version of a key element of the upcoming LISA (Laser Interferometer Space Antenna) mission. The LISA mission, a collaboration between ESA (the European Space Agency) and NASA, will use infrared lasers to detect gravitational waves, […]
A team of astronomers has employed a cutting-edge, artificial intelligence-assisted technique to uncover rare astronomical phenomena within archived data from NASA’s Hubble Space Telescope. The team analyzed nearly 100 million image cutouts from the Hubble Legacy Archive, each measuring just a few dozen pixels (7 to 8 arcseconds) on a side. They identified more than […]
At the heart of our own galaxy, there is a dense thicket of stars with a supermassive black hole at the very center. NASA’s Nancy Grace Roman Space Telescope will provide the deepest-ever view of this zone, revealing stars, planets, and unique objects that resist definition. Based on the input of astronomers from across the […]
It may be one of the most iconic sights in the night sky, but astronomers have never seen the Helix Nebula like this before.

“The knowledge of these will ultimately help us understand the formation of the first stars and planets and how our own Milky Way came into being.”
…
Some newly found stars in a small galaxy called Sextans A are forming without some of the usual “ingredients,” raising questions about how the early universe evolved.
…
There may not be as nearly as many small galaxies in the early universe as astronomers predict there should be, which has big implications for the story of how our universe grew up.
…
“These nine objects are special.”
Both NASA’s James Webb Space Telescope and Chandra X-ray Observatory caught these two galaxies in a close embrace.
…
The galaxy cluster appears hotter and more mature than it should for its young age, challenging what we think we know about how these cities of galaxies form.
