Martian dust devil analogues in the Mojave Desert
In the Mojave Desert, the sun beats down on the ground and makes pockets of low pressure. Cool air rushes into these areas, where it warms and rises, creating vortices that pick up dust. These types of dust devils aren't ...

Astronomers observe outburst of the young magnetar Swift J1818.0–1607
Using various space telescopes, European astronomers have performed deep X-ray and radio observations of a young magnetar known as Swift J1818.0–1607 during its outburst. Results of the observational campaign, published ...
Surprise kilonova upends established understanding of long gamma-ray bursts
For nearly two decades, astrophysicists have believed that long gamma-ray bursts (GRBs) resulted solely from the collapse of massive stars. Now, a new study upends that long-established and long-accepted belief.

'Black widow' PSR J1544+4937 investigated in detail
Indian astronomers have performed long-term radio observations of a "black widow" millisecond pulsar known as PSR J1544+4937. Results of the observational campaign, published November 25 on the arXiv pre-print server, shed ...
Long-lived lakes reveal a history of water on Mars
The northern hemisphere of Mars is divided into two broadly distinctive areas: the smooth northern lowlands and the pockmarked southern highlands. The region of Arabia Terra sits along the transition between these two regions ...
