NASA has announced that the Nancy Grace Roman Space Telescope is all set for a September launch.
This Earth Day, we reflect on our home planet and look at Earth from space through history.
Four Navy divers made a contribution to the historic Artemis 2 moon mission, welcoming its astronauts home to Earth and making sure they were safe and healthy.
The dependable Hubble Space Telescope has been in orbit for more than 35 years now. It's at a point where it can reexamine objects it observed decades ago and can uncover changes that have transpired over human timescales. This is an impressive feat for a telescope that was projected to last only 15 years.
The Federal Aviation Administration has temporarily grounded Blue Origin's New Glenn rocket, which failed to deliver a satellite to the proper orbit during its third-ever launch on Sunday (April 19).
The Proba 3 mission flies two spacecraft in precise formation to create an artificial eclipse and obtain close views of the solar wind as it leaves the Sun.
The moon is visible in the daytime sky as it grows thicker ahead of the full phase on May 1.
Lyrid meteors were photographed blazing through Earth's atmosphere on the nights surrounding the April 22 peak.
Scientists have been debating for decades whether Mars once held a vast ocean covering a large part of its northern face. To prove the idea, they’ve been looking for a “bathtub ring” - a distinct, level shoreline that shows where water once stood. But, despite years of looking, they’ve only been able to find a very distorted potential shoreline whose height deviates by several kilometers - not exactly great evidence of a stable water level. But, according to a new paper in Nature from Abdallah Zaki and Michael Lamb of CalTech, what scientists should have been looking for wasn’t a bathtub ring, but a continental shelf.
The two most puzzling rings around Uranus are gradually giving up their secrets, only to deepen the mystery of the Uranian system.
Happy Earth Day, 22 April – a global call to act and protect our planet. At the European Space Agency, that action begins in orbit, where satellites deliver a continuous, global view of Earth and track environmental change. Working with partners, ESA turns this stream of data into actionable information through its FutureEO programme, helping governments and communities respond faster and more effectively to climate-driven risks.
The search for life beyond Earth has traditionally focused on exoplanets orbiting Sun-like stars, which is a G-type star. However, low-mass stars, which are designated as K-type and M-type stars, have rapidly become a target for astrobiology, primarily due to their much longer lifetimes. This also means the habitable zone (HZ), which is the distance from a star where liquid water could exist, is much smaller than our solar system’s HZ, and is referred to as the liquid water habitable zone (LW-HZ). In contrast, another type of HZ that involves a star’s ultraviolet (UV) radiation potentially enabling life-harboring conditions is known as UV-HZ.
NASA's Nancy Grace Roman Space Telescope, which is set to launch this coming September, has the potential to show us pockets of the cosmos we've yet to touch.
As we make our way through the latest solar maximum period, scholars and scientists are looking to similar events in the past to learn more about ancient bouts of solar activity. In particular, they want to know more about solar proton events (SPEs). These outbursts of high-energy particles get triggered by flares and coronal mass ejections.
NASA Force aims to recruit industry talent to the space agency for relatively short stints. Applications are open now in the wake of the Artemis 2 moon mission.
Sick of light pollution tainting your astrophotography? Capture nebulas, galaxies and more with $700 off this powerful, portable Unistellar Odyssey Pro smart telescope.
Astronomers have discovered that jets from a cannibalistic black hole are erupting with the power of 10,000 suns.
Astronomers have located the edge of the Milky Way’s star-forming disk for the first time, showing that star formation is focused within 40,000 light-years of our galactic center.
A half moon passes close to Jupiter on April 22, creating a striking scene.
