Marsquakes and meteorite hits show Mars has a dense liquid metal core

Mars’ dense liquid iron core is wrapped in a layer of molten rock, which threw off previous measurements of the Red Planet’s heart.

How quantum ‘squeezing’ will help LIGO detect more gravitational waves

An upgrade to LIGO that comes from exploiting a quantum rule known as the Heisenberg uncertainty principle makes it easier to detect spacetime ripples.

A rare glimpse at a relatively nearby supernova offers clues to how stars die

Thanks to its home in the Pinwheel galaxy, a favorite of amateur astronomers, researchers have monitored SN 2023ixf since shortly after it exploded.

Giant planet ‘destabilization’ may have coincided with the birth of Earth’s moon

New meteorite data suggest the orbits of the giant planets abruptly changed about 60 million to 100 million years after the solar system started forming.

Here’s how citizen scientists can help during the 2024 solar eclipse

The sun will be near the peak of its activity cycle during the eclipse on April 8, 2024, making it a great time to crowdsource solar research.

Here’s another strike against Venus having copious lightning

Past data and the Parker Solar Probe’s new discovery of weird whistler waves overturn the idea that Venus’ hellish atmosphere has a lot of lightning.

The black hole–powered jet in galaxy M87 is making stars explode

Hubble Space Telescope data show a surprising number of nova blasts along the jet of high-speed gas coming from the galaxy M87.

NASA’s first look at a sample from asteroid Bennu reveals life’s building blocks

Scientists have begun to analyze roughly 250 grams of Bennu, which could offer insight into solar system formation and life’s origins on Earth.
