AI reshapes how we observe the stars

AI tools are transforming how we observe the world around us—and even the stars beyond. Recently, an international team proved that deep learning techniques and large language models can help astronomers classify stars ...

Euclid opens data treasure trove, offers glimpse of deep fields

On 19 March 2025, the European Space Agency's Euclid mission releases its first batch of survey data, including a preview of its deep fields. Here, hundreds of thousands of galaxies in different shapes and sizes take center ...

Hubble sees a spiral and a star in the constellation Virgo

This NASA/ESA Hubble Space Telescope image features a sparkling spiral galaxy paired with a prominent star, both in the constellation Virgo. While the galaxy and the star appear to be close to one another, even overlapping, ...

Would we know if a supernova was about to hit the Earth?

We know that regular supernovas pose no existential threat to life on Earth in the near-term. But there are other varieties of supernova that are a little bit harder to predict, and a little bit harder to spot.

Astro-challenge: Following Venus from dusk until dawn

Up for a challenge? If skies are clear, you may be able to complete a rare feat of visual athletics this coming weekend, and follow Venus on its trek from the evening into the morning sky.

DESI releases largest 3D map of the universe to date

The Dark Energy Spectroscopic Instrument (DESI) is mapping millions of celestial objects to better understand dark energy—the mysterious driver of our universe's accelerating expansion. Today, the DESI collaboration released ...

Oxygen discovered in most distant known galaxy

Two different teams of astronomers have detected oxygen in the most distant known galaxy, JADES-GS-z14-0. The discovery, reported in two separate studies, was made possible thanks to the Atacama Large Millimeter/submillimeter ...

FAST detects new ultra-faint dwarf galaxy

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have detected a new ultra-faint dwarf galaxy, which turned out to be gas-rich. The finding was reported in a research paper published ...
