Exoplanets
Webb Finds a Hidden Planet Around Beta Pictoris
NASA's James Webb Space Telescope has discovered Beta Pictoris d, a giant exoplanet in one of the most studied young planetary systems in the Milky Way. Beta Pictoris was already famous for two directly imaged planets and a bright debris disc, but the third world was hidden in the glare and dust.
The important part is how it was found. Astronomers used Webb's NIRSpec instrument to pick out the chemical fingerprint of the planet's atmosphere, rather than simply looking for a bright dot. This could become a powerful way to detect planets in messy, dusty systems where ordinary imaging struggles.
Galaxies
Hubble Shows Andromeda's Star Formation Slowing Down
Hubble data suggest that star formation in the Andromeda galaxy has been declining for about 500 million years, with a sharper fall in the last 40 million years. Andromeda is the nearest large spiral galaxy to our own Milky Way, so this is not just a distant curiosity: it is a close comparison for how large galaxies change over time.
By studying millions of stars across Andromeda, astronomers can reconstruct when different regions were actively forming new stars. The result is a picture of a galaxy gradually becoming quieter, which helps researchers understand the long-term future of spiral galaxies.
Black Holes
A Wandering Black Hole Gives Itself Away
NASA's Swift observatory has helped identify a supermassive black hole far from the centre of its host galaxy. It was spotted because a star passed too close and was torn apart, producing a bright tidal disruption event.
Most supermassive black holes sit in galactic centres, so an active one more than 30,000 light-years from the middle of its galaxy is unusual. Events like this can reveal otherwise invisible black holes and may help astronomers understand how galaxy mergers scatter massive black holes into unexpected places.
Star Birth
ALMA Finds Organic-Rich Stellar Cradles Inside a Supernova Remnant
ALMA has detected hot molecular cores inside a supernova remnant for the first time. These warm, dense pockets of gas surround newborn stars and contain a rich mix of organic molecules.
The discovery is a reminder that star formation can happen in surprisingly harsh places. Even in the aftermath of a stellar explosion, complex chemistry can survive or rebuild, giving astronomers a fresh look at how new stars and their chemical ingredients emerge.
Deep Universe
Webb Follows the Family Tree of Mysterious Red Objects
New Webb research is exploring what the early Universe's mysterious little red dots become as the cosmos ages. These compact red sources were first highlighted by Webb's deep observations and have become one of the telescope's most intriguing early-Universe puzzles.
Astronomers are testing whether these objects are young galaxies, growing black holes, or a mixture of both. Pinning down their identity matters because they may show how the first generations of galaxies and black holes grew so rapidly after the Big Bang.
Milky Way
Euclid Maps the Crowded Heart of Our Galaxy
ESA's Euclid mission has released an exceptionally detailed visible-light view of the Milky Way's galactic bulge, packed with more than 60 million stars. Although Euclid's main job is to map distant galaxies and the dark Universe, this special observation shows how powerful it is for crowded star fields too.
The survey can support microlensing studies, where tiny changes in starlight reveal otherwise hidden planets. That makes it a useful preview of the kind of planet-hunting work NASA's Roman Space Telescope is expected to do after launch.
Coming Soon
Roman Space Telescope Nears Launch
NASA lists the Nancy Grace Roman Space Telescope for launch on 30 August 2026. Roman is designed to tackle dark energy, dark matter, exoplanets and wide-field infrared astronomy, with a field of view far larger than Hubble's.
If the launch goes ahead as planned, Roman should become one of the decade's headline astronomy missions. It will be especially important for galaxy surveys and for finding planets through microlensing towards the centre of the Milky Way.
