An Anomalous SETI Signal
6.02.2011

No one knows for sure what caused this signal. There is a slight possibility that it just might originate from an extraterrestrial intelligence. The bright colors on the blue background indicate that an anomalous signal was received here on Earth by a radio telescope involved in a Search for Extraterrestrial Intelligence (SETI).

Orion Launch
5.12.2014

Headed for two orbits of planet Earth and a splashdown in the Pacific, Orion blazed into the early morning sky on Friday at 7:05am ET. The spacecraft was launched atop a United Launch Aliance Delta IV Heavy rocket from Cape Canaveral Air Force Station in Florida.

Announcing Comet Catalina
18.08.2015

Will Comet Catalina become visible to the unaided eye? Given the unpredictability of comets, no one can say for sure, but it seems like a good bet. The comet was discovered in 2013 by observations of the Catalina Sky Survey.

Int Ball Drone Activated on the Space Station

What if you were followed around by a cute floating ball that kept taking your picture? Then you might be an astronaut on today's International Space Station (ISS). Designed by the Japan Aerospace...

Attack of the Laser Guide Stars

Dodging powerful laser beams, a drone captured this stunning aerial view. The confrontation took place above the 8.2 meter diameter Very Large Telescopes of the Paranal Observatory on planet Earth. Firing during a test...

A Stellar Jewel Box: Open Cluster NGC 290
13.10.2019

Jewels don't shine this bright -- only stars do. Like gems in a jewel box, though, the stars of open cluster NGC 290 glitter in a beautiful display of brightness and color. The photogenic cluster, pictured here, was captured in 2006 by the orbiting Hubble Space Telescope.

NGC 7293: The Helix Nebula
14.10.2021

A mere seven hundred light years from Earth, toward the constellation Aquarius, a sun-like star is dying. Its last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution.

Find the New Moon

Can you find the Moon? This usually simple task can be quite difficult. Even though the Moon is above your horizon half of the time, its phase can be anything from crescent to full.

Flying Over Asteroid Eros West End
17.04.2000

The robot spacecraft NEAR Shoemaker continues to orbit asteroid Eros. This condensed 40-minute long time-lapse sequence taken last month shows what it looks like to pass within 200 kilometers of Eros' west end. The north pole of the rotating mountain is toward the bottom of the picture.

A Massive Cluster In A Young Universe
21.08.1998

Conventional theories suggest that this cluster of galaxies should not exist. Each fuzzy spot in this false-color Hubble Space Telescope image of the central regions of a newly discovered galaxy cluster is a galaxy similar in mass to our own Milky Way.
