Volcano-like rupture could have caused magnetar slowdown

On Oct. 5, 2020, the rapidly rotating corpse of a long-dead star about 30,000 light years from Earth changed speeds. In a cosmic instant, its spinning slowed. And a few days later, it abruptly started emitting radio waves.

Starry tail tells the tale of dwarf galaxy evolution

A giant diffuse tail of stars has been discovered emanating from a large, faint dwarf galaxy. The presence of a tail indicates that the galaxy has experienced recent interaction with another galaxy. This is an important clue ...

Perseverance takes a selfie to show off some of its samples

One of the main jobs for the Perseverance Mars rover past few weeks has been collecting carefully selected samples of Mars rock and soil. These samples have been placed and sealed in special sample tubes and left in well-identified ...

Video: The Sample Transfer Arm: A helping hand for Mars

The mission to return Martian samples back to Earth will use a European 2.5 meter-long robotic arm to pick up tubes filled with precious soil from Mars and transfer them to a rocket for an historic interplanetary delivery.

Instrument on JWST has gone offline

The JWST is having a problem. One of its instruments, the Near Infrared Imager and Slitless Spectrograph (NIRISS), has gone offline. The NIRISS performs spectroscopy on exoplanet atmospheres, among other things.

Nine new and exotic creatures for the pulsar zoo

Researchers using MeerKAT in South Africa have discovered nine millisecond pulsars, most of them in rare and sometimes unusual binary systems, as the first result of a targeted survey. An international team with significant ...

BepiColombo and Solar Orbiter compare notes at Venus

The convergence of two spacecraft at Venus in August 2021 has given a unique insight into how the planet is able to retain its thick atmosphere without the protection of a global magnetic field.

Astronomers use novel technique to find starspots

Astronomers have developed a powerful technique for identifying starspots, according to research presented this month at the 241st meeting of the American Astronomical Society.
