Fifteen years ago, human hands touched NASA’s Hubble Space Telescope for the last time. As astronauts performed finishing tasks on the telescope during its final servicing mission in May 2009, they knew they had successfully concluded one of the most challenging and ambitious series of spacewalks ever conducted. But they couldn’t have known at the […]

NASA’s Hubble Space Telescope team has released a new downloadable e-book in the Hubble Focus series, called “Hubble Focus: The Dark Universe.” This e-book highlights the mission’s recent discoveries about two mysterious components of our universe, known as dark energy — an unexplained cosmic pressure that’s speeding up the universe’s expansion — and dark matter, […]

Amid a site teeming with new and young stars lies an intricate substructure. A team of astronomers has used NASA’s James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star […]

The highly competitive NASA Hubble Fellowship Program (NHFP) recently named 24 new fellows to its 2024 roster. The program fosters excellence and inclusive leadership in astrophysics by supporting a diverse group of exceptionally promising and innovative early-career astrophysicists. The NHFP enables outstanding postdoctoral scientists to pursue independent research in any area of NASA Astrophysics, using […]

Maybe you read about them in the papers–amateur astronomers in Japan, Russia, France, Finland, and the United States have been pulling all-nighters to spot extraordinary exoplanets, planets orbiting stars other than the Sun.  NASA’s UNITE project holds these planetary stakeouts several times every month, and you can join in! This October, the UNITE team undertook a […]

This image of the softly luminous spiral galaxy UGC 11105 is from the NASA/ESA Hubble Space Telescope. It lies about 110 million light-years from Earth in the constellation Hercules. Astronomers have different ways of quantifying how bright celestial objects are. Apparent magnitude is one of those methods. It describes how bright an object appears to an observer […]

Ten teams from around the world have been named the Global Winners of the 2023 NASA International Space Apps Challenge. The Challenge is the largest annual global hackathon, and gives participants the opportunity to engage with real world problems we face on Earth and in space.
