Newly discovered asteroid to fly past Earth this week

The space rock has been given the name 2026 JH2 and is thought to be up to around 35 metres wide - around the length of a 5-a-side football pitch.

Waterworn chaos on Mars

Shalbatana Vallis is an impressive channel near Mars’s equator. It is 1300 km in length - around the length of Italy. Formed formed around 3.5 billion years ago, when huge quantities of groundwater rose up to Mars’s surface.

Neptune's moon Nereid may be original survivor of Triton's arrival

Observations suggest that Nereid is no party crasher like Triton and likely survived by escaping into its extreme, elliptical orbit around Neptune.

Fermi Identifies Hidden Engine behind Superluminous Supernovae

New gamma-ray observations from NASA’s Fermi Space Telescope suggest ultra-magnetic neutron stars called magnetars could be fueling superluminous supernovae.

Violent Collision May Have Destroyed Milky Way’s First Stellar Disk

New simulations suggest a violent collision 11 billion years ago reshaped our Galaxy and triggered a burst of star formation.

Stardust in Antarctica shows Earth crossed a supernova cloud

Our solar system has been moving through the local interstellar cloud, left by a supernova, for over past 80,000 years.

NASA Warns Earth Is Threatened by 15,000 Undetected Asteroids

Nearly 15,000 “city-killer” asteroids are still missing from our maps. Scientists know they’re out there. They just can’t see them yet.

Newton's Law of Gravity Just Passed Its Biggest Test Ever

The motion of galaxy clusters in the distant Universe has just yielded the largest-scale test yet of the laws of gravity.

NASA Says Strange Red Dots Are an Unknown Class of Object

There’s a fresh twist in the mystery of the “little red dots.” Astronomers say they’ve found a new specimen, which they’re calling an “X-ray dot.

Surprising alien worlds with ever-shifting orbits

A newly observed planetary system, dubbed TOI-201 is an outlier. Surprisingly, observations of the system’s three known planets have revealed orbits that change in real time. That is to say, they shift on human timescales.

This strange planet pair shouldn’t exist, but it does

A bizarre planetary pairing 190 light-years away is challenging everything  -  a “lonely” hot Jupiter — typically found without nearby companions — is sharing its system with a smaller mini-Neptune tucked even closer to the star.

Webb space telescope finds a giant galaxy that doesn’t spin

Astronomers using the James Webb Space Telescope have spotted something that shouldn’t exist—at least not so early in the universe. A massive galaxy, formed less than 2 billion years after the Big Bang, appears to have no rotation at all.

The Universe’s biggest black holes may be forged in violent mergers

The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes are likely “cosmic recyclers” .

Over 10,000 new exoplanet candidates revealed by TESS

NASA has uncovered over 10,000 new candidate planets across our galaxy. Scientists found them through a single survey of data captured by the TESS space telescope.

Tiny world with an atmosphere in outer solar system

Astronomers have spotted a tiny world with an atmosphere beyond the orbit of Neptune. It should be too small for an atmosphere to be possible.
