IC443's Neutron Star
15.12.2000

Using x-ray data from the orbiting Chandra Observatory along with radio data from the Very Large Array, a team of researchers has discovered evidence for a new example of one of the most bizarre objects known to modern astrophysics -- a neutron star.

Phases of Venus
17.03.2017

Just as the Moon goes through phases, Venus' visible sunlit hemisphere waxes and wanes. This composite of telescopic images illustrates the steady changes for the inner planet, seen in the west as the evening star, as Venus grows larger but narrows to a thin crescent from December 20, 2016 through March 10.

Shoreline of the Universe

Today, the Sun crosses the celestial equator heading south at 03:09 Universal Time. Known as an equinox, this astronomical event marks the first day of autumn in the northern hemisphere and spring in the south. Equinox means equal night.

North America and the Pelican
1.12.2017

Fans of our fair planet might recognize the outlines of these cosmic clouds. On the left, bright emission outlined by dark, obscuring dust lanes seems to trace a continental shape, lending the popular name North America Nebula to the emission region cataloged as NGC 7000.

Phases of Venus
