New findings from the ALMA telescope have revealed that planets are born in much smaller protoplanetary disks than astronomers suspected, some of which would fit with the orbit of Earth.

The space telescope's image of a odd-looking spiral galaxy is, in reality, two distant galaxies overlapping each other.

Hiroyasu Tsukamota has developed a deep-learning-based guidance and control framework called Neural-Rendezvous that could allow spacecraft to safely encounter interstellar objects.

The crew of SpaceX's pioneering Fram2 mission includes a polar explorer, a marine technology scientist, a filmmaker and a bitcoin magnate.

There are a number of ways that exoplanets have been discovered over recent years but a team of astronomers have been exploring other ways. One particular exciting method is to hunt for them by finding their magnetospheres! Earth and Jupiter are a great example of planets that are surrounded by strong magnetospheres that interact with solar activity and when they do, they release radio emissions. The team of researchers have been demonstrating just how they could detect Jupiter’s radio emissions using simulated data. Not only would they be able to detect it, but they could also measure its rotation and even detect interactions with its moons!

For over a decade, ESA’s Gaia mission has mapped our galaxy with stunning precision—rewriting the story of the Milky Way. As its mission enters a new phase, we look back at its most groundbreaking discoveries.

When the James Webb Space Telescope was launched in December 2021, one of its primary purposes was to see the first galaxies in the Universe forming just a few million years after the Big Bang. In true JWST style though, it has surpassed all expectations and now, a team of astronomers think they have gone even further back, seeing one galaxy clearing the early fog that obscured the Universe! The image represents a point in time 330 million years after the Big Bang and reveals a bright hydrogen emission from the fog surrounding a galaxy. It was somewhat unexpected though as current models predict it would have been blown away long ago!

Here's everything you need to know to make the most of the partial solar eclipse on March 29, as the moon takes a 'bite' out of the sun.

The outer planets remain somewhat of a mystery and Neptune is no exception. Voyager 2 has been the only probe that has visited the outermost planet but thankfully the James Webb Space Telescope is powerful enough to reveal it in all its glory. With its cameras regularly fixed on Neptune it has even picked up auroral activity in some of its latest images. The data was gathered back in 2023 using Webb’s Near-Infrared spectrograph which detected the tell tale sign of auroral activity, an emission line of trihydrogen cation. The element appears on other giant planets too when aurora are present.

The first image from a new Italian Earth observation satellite mission was published today: a high-resolution image of a strip of the Italian peninsular showing the city of Rome at a resolution of 2.66 metres. This is three times higher than the resolution currently available for systematic acquisition over Italy.

NASA and Boeing are still working on the thruster issues that Starliner experienced on its first crewed flight last year, so the capsule's next liftoff is a ways off yet.

Can the cosmic rays bombarding the lunar surface be used to identify subsurface water ice deposits? This is what a recent study and iposter presented at the 56th Lunar and Planetary Science Conference (LPSC) hopes to address as a team of researchers developed a novel method called the Cosmic Ray Lunar Sounder (CoRaLS) capable of detecting subsurface lunar water ice deposits that are elusive to current radar systems. This study has the potential to help expand the human presence on the Moon since water ice deposits are currently being focused on the permanently shadowed regions (PSRs) of the Moon for the upcoming Artemis missions.

The makeup of the SpaceX Crew-11 mission to the International Space Station was announced publicly Thursday evening and it includes three astronauts who were previously assigned to other missions.

What can Venus-like exoplanets, also known as exoVenuses, teach us about our own solar system and potentially finding life beyond Earth, and how can the planned Habitable Worlds Observatory (HWO) provide these insights? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC) hopes to address as a team of scientists discussed the difficulties of studying exoVenuses and how HWO can help alleviate these challenges by directly imaging them. This study has the potential to help astronomers develop advanced methods for better identifying and understanding potentially life-harboring exoplanets throughout the cosmos.

Way back in 2006, the Spitzer Space Telescope (SST) took an infrared look at a strange object called Herbig-Haro 49/50. It's a jet flowing away from a hot young star. The Spitzer image showed a fuzzy blob at the end of the jet. Was it part of the jet, or something more distant? Recently, the James Webb Space Telescope (JWST) focused its infrared eye on the same object and sent home a fantastic snapshot of this cosmic tornado. It also answered the question about the blob: it turns out to be a distant galaxy, itself bursting with hot young stars.

The U.S. Space Force has certified ULA's new Vulcan Centaur rocket to launch national security missions, doubling the number of providers for such flights.

Mars is cold and dry, but long ago, it was warmer and wetter. Today, its geology is driven by wind and sand, but it was also shaped by water and maybe even glaciers. Glacial activity on Mars was long assumed to be dry, with glaciers frozen right to their beds, scouring the landscape of the Red Planet. But now, researchers think they've found evidence of subglacial melting, where a layer of water forms under the glacier, helping to form various features on Mars.
