What are these little red dots (LRDs)?

What's happening in the sky?

This is the mess that is left when a star explodes.

A team led by the Institute of Space Sciences (ICE-CSIC) analyzed samples of C-type asteroids in a recent study. Their findings support the idea that these asteroids can serve as a crucial source of materials if and when asteroid mining is realized.

Supermassive black holes have a reputation for devouring everything in sight, but new observations from the Atacama Large Millimetre/submillimetre Array reveal they can be surprisingly picky eaters. Even when galaxy mergers deliver enormous amounts of cold molecular gas directly to a black hole’s doorstep, many choose to nibble rather than gorge raising questions about what triggers feeding episodes. The discovery suggests black hole growth during galaxy collisions may be far more inefficient and episodic than we previously thought.

A humungous shark that lived 115 million years ago surpassed the size of modern-day great whites, paleontologists discovered

It took 125 years, but in 2025 a team of mathematicians discovered the solution to a long-puzzling problem about the equations that govern the behaviour of particles in a fluid

Data from NASA’s James Webb Space Telescope and Chandra X-ray Observatory come together in this eye-catching photo of colliding spiral galaxies released on Dec. 1, 2025.

Beijing is set to tighten China’s rules for humanlike artificial intelligence, with a heavy emphasis on user safety and societal values

There is a state of relaxation that few of us spend much time in, but which comes with profound well-being benefits. With healthier ageing, reduced risk of disease and feeling more energised all on offer, here's how to get there

The highlights of spaceflight in 2025 have included missions to explore the Moon, Mars, and the Sun — and more is coming in the New Year.

The post Spaceflight for Astronomy — A Look Back and Ahead appeared first on Sky & Telescope.

The Linac Coherent Light Source in California has been firing record-breaking X-ray pulses for years, but now it’s due for a shutdown and an upgrade. When it is turned back on, it will be even more powerful
