Earthquakes and the seismic waves they generate provide some of the best clues to Earth’s interior. To extend that success to other worlds, scientists placed seismometers on the Apollo missions to the moon and on the Viking Mars landers, which reached Mars in 1976. Though the Apollo detectors proved a resounding success, Viking’s results on […]

SpaceX reported a bigger quarterly profit than expected Tuesday as its satellite communications operations and its business of leasing computing power to other companies boomed.

Water isn’t always as it seems. Under extreme conditions, such as those found on other planets, it has been discovered to change its atomic structure, giving it the means to alter its appearance and other properties.

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have completed two of the largest cosmological simulations ever performed. Each simulation modeled the evolution of 13.4 trillion dark matter particles across a region 28.6 billion light-years wide.

Pulsars are rapidly rotating neutron stars, the extremely dense cores left behind when massive stars explode. Astrophysicists have recently observed a pulsar rotating over 300 times per second that appeared to be slowing down unusually quickly.

Some supermassive black holes rapidly consume surrounding matter while simultaneously firing powerful streams of plasma into space at nearly the speed of light. However, this creates a physical puzzle: rapid feeding is expected to form a cold, flat accretion disk around the black hole, which prevents powerful jets from forming.

The interstellar comet 3I/ATLAS brought material from another planetary system within reach of our telescopes, but reading its chemistry poses a problem. Energetic particles encountered during its journey through space may have changed its outer layers, so how much of what astronomers detect still reflects the comet’s birthplace?
