Habitable worlds may be far more common than thought, Israeli study says

Published in the peer-reviewed The Astrophysical Journal, the research focuses on tidally locked planets, worlds that always show the same face to their star.

 Life beyond Earth may exist in far stranger places than scientists once thought, a new study suggests. January, 22.

Astronomers spot white dwarf star creating a colorful shockwave

In the shockwave, a red hue represented hydrogen, green represented nitrogen, and blue represented oxygen residing in interstellar space.

The central square image, taken with the MUSE instrument on ESO's Very Large Telescope, shows shock waves around the dead star RXJ0528+2838.

NASA rover detects electrical discharges - 'mini-lightning' - on Mars

The six-wheeled rover, exploring Mars since 2021 at a locale called Jezero Crater in its northern hemisphere, picked up these electrical discharges in audio and electromagnetic recordings.

NASA releases images of comet 3I/ATLAS, rejects alien spacecraft 'rumors'

While the comet's precise point of origin remains unclear, the NASA scientists said they believe it hails from a solar system older than our own, which formed about 4.5 billion years ago.

This image of interstellar comet 3I/ATLAS was captured by the Hubble Space Telescope’s Wide Field Camera, July 21, 2025.

Israeli scientists propose new way to ‘hear’ the universe’s dark matter

Dark matter is a type of matter that does not emit, absorb, or reflect light, making it invisible to telescopes.

 This is an artist's impression of a runaway supermassive black hole that was ejected from its host galaxy as a result of a tussle between it and two other black holes. As the black hole plows through intergalactic space it compresses gas and forms stars (Illustrative).
