The final release of data from the Dark Energy Survey widens tensions in our understanding of the cosmic evolution.

Scientists analyzed more than 100 million image cutouts from a Hubble Space Telescope archive and found hundreds of previously undiscovered objects

Why are SMBH in the early Universe so massive? According to astrophysical models, these extraordinarily large SMBH haven't had time to become so massive. Super-Eddington accretion might explain it, but can it explain a very unusual early SMBH recently discovered?

It's been about one millennia since humans directly observed a core-collapse supernova in the Milky Way. That's strange, since there should be 1 or 2 every century. By working with neutrino detectors, the Vera C. Rubin Observatory should be able to detect far more supernovae.

NASA’s James Webb Space Telescope’s 2024 NIRCam image shows protostar EC 53 circled. Researchers using new data from Webb’s MIRI proved that crystalline silicates form in the hottest part of the disk of gas and dust surrounding the star — and may be shot to the system’s edges.

The remains of a teenage boy who lived around 27,000 years ago suggest he was attacked by a cave bear—some of the first direct evidence of a predator attacking an ancient human

Watch the keynote address by ESA Director General Josef Aschbacher at the 18th European Space Conference in Brussels.

The European Space Conference is a key strategic event bringing together representatives from ESA, the European Commission, industry, national space agencies and other European institutions to discuss the future of Europe in space.

A team of astronomers have used a new AI-assisted method to search for rare astronomical objects in the Hubble Legacy Archive. The team sifted through nearly 100 million image cutouts in just two and a half days, uncovering nearly 1400 anomalous objects, more than 800 of which had never been documented before.

Lately we’ve been reporting about a series of studies on the Habitable Worlds Observatory (HWO), NASA’s flagship telescope mission for the 2040s. These studies have looked at the type of data they need to collect, and what the types of worlds they would expect to find would look like. Another one has been released in pre-print form on arXiv from the newly formed HWO Technology Maturation Project Office, which details the technology maturation needed for this powerful observatory and the “trade space” it will need to explore to be able to complete its stated mission.

The European Space Agency discussed plans for its record budget as the 18th European Space Conference began in Brussels, Belgium on 27 January.

There’s a bright side to every situation. In 2032, the Moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%), but non-negligible. And scientists are starting to prepare both for the bad (massive risks to satellites and huge meteors raining down on a large portion of the planet) and the good (a once in a lifetime chance to study the geology, seismology, and chemical makeup of our nearest neighbor). A new paper from Yifan He of Tsinghua University and co-authors, released in pre-print form on arXiv, looks at the bright side of all of the potential interesting science we can do if a collision does, indeed, happen.
