No matter where on Earth you stand, if you have a view of the night sky, and if it is dark enough, you can see the Milky Way. The Milky Way is our home, and its faint clouds of light and shadow have inspired human cultures across the globe. And yet, our view of the Milky Way is limited by our perspective. In many ways, we have learned more from other galaxies than from our own. But when the Gaia spacecraft launched in 2013, all of that changed.

Solar eclipse US weather forecast: Best places to see the moon 'bite' the sun tomorrow
A partial solar eclipse is coming this weekend, but weather could be an issue for many hoping to get a glimpse of the moon "taking a bite" out of the sun.
Surprise X-class solar flare from emerging sunspot triggers radio blackouts across the Americas
"Further strong activity is likely!"
Revealing Proxima Centauri's Extreme Flares
In this age of exoplanet discovery, the flaring of red dwarf stars (M-dwarfs) has taken on new importance. M-dwarfs are known to host many terrestrial planets in their putative habitable zones. The problem is the flaring could make their habitable zones uninhabitable.
NASA astronaut who gave up seat for Starliner crew takes command of SpaceX Crew-11 flight to ISS
Zena Cardman,who was removed from an ISS launch to facilitate the return to Earth of Starliner's first crew, will command SpaceX's upcoming Crew-11 mission to the station.

Exoplanet nurseries around infant stars can be much smaller than expected: 'It is astonishing'
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.
James Webb Space Telescope discovers 2 galaxies forming breathtaking 'cosmic lens': Space photo of the day
The space telescope's image of a odd-looking spiral galaxy is, in reality, two distant galaxies overlapping each other.
This spacecraft swarm could spot interstellar visitors zipping through our solar system
Hiroyasu Tsukamota has developed a deep-learning-based guidance and control framework called Neural-Rendezvous that could allow spacecraft to safely encounter interstellar objects.

Detecting Exoplanets by their Magnetospheres
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!
Gaia: Rewriting the story of the Milky Way

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.
Webb Sees an Early Galaxy Blowing Away the Cosmic Fog
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!
Don't miss the partial solar eclipse tomorrow: Where, when and how to see it
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.
Webb Sees Neptune's Auroras for the First Time
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.
IRIDE first image presented at ESA–ESRIN
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.
Boeing's next Starliner launch for NASA could slip to early 2026 after fixes
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.

CoRaLS Instrument Could Identify Buried Lunar Ice
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.
