On Tuesday, Oct. 6, catch the thin crescent Moon high in the eastern sky before dawn. Just above the Moon, you’ll see the planet Jupiter. Below the Moon, the bright star Regulus will be shining.

A record-breaking X-ray flash may reveal the birth of a magnetar
Astronomers have found strong evidence that some mysterious, minutes-long X-ray flashes are produced when two neutron stars collide and create a magnetar. One record-setting event glowed in X-rays for nearly 10 minutes, potentially opening a new way to find these extreme cosmic mergers.

Water ice deposits on Mars hold important records of climate. Near the north pole, water ice is exposed within the residual polar cap and in isolated crater deposits. The physical properties of ice can be derived by analyzing its spectral reflectance, which depends on grain size, dust content, and v
