La Nina Watch
20.07.1998

Goodbye El Niño. Hello La Niña? Scientists are watching to see if an evolving pool of relatively cool water in the mid-Pacific Ocean will develop into a full "La Niña". Over the past several months, the water temperature in the Equatorial Pacific Ocean has been doing a flip-flop.

In the Center of the Omega Nebula
8.02.2004

In the depths of the dark clouds of dust and molecular gas known as the Omega Nebula, stars continue to form. The above image from the Hubble Space Telescope's Advanced Camera for Surveys shows exquisite detail in the famous star-forming region.

Elliptical Galaxy M87
16.06.2004

Elliptical galaxy M87 is a type of galaxy that looks much different than our own Milky Way Galaxy. Even for an elliptical galaxy, though, M87 is peculiar. M87 is much bigger than an average...

NGC 1531/2: Interacting Galaxies
1.03.2005

This dramatic image of an interacting pair of galaxies was made using 8-meter Gemini South telescope at Cerro Pachon, Chile. NGC 1531 is the background galaxy with a bright core just above center and NGC 1532 is the foreground spiral galaxy laced with dust lanes.

Gemini North Telescope Inaugurated
29.06.1999

A new mammoth telescope has begun to inspect the northern sky. The 8-meter Gemini North telescope, pictured above, was dedicated last week in Hawaii, with images documenting its unprecedented abilities being released. Within two years, sister telescope Gemini South will begin similar observations of the southern sky from Chile.

Four Supernova Remnants
28.07.2006

These four panels show x-ray images of expanding cosmic debris clouds, tens of light-years across, in nearby galaxy the Large Magellanic Cloud. The supernova remnants (SNRs) are the results of two types of stellar...

Elliptical Galaxy NGC 4881 in Coma
21.11.1999

Elliptical galaxies are unlike spiral galaxies and hence unlike our own Milky Way Galaxy. The giant elliptical galaxy named NGC 4881 on the upper left lies at the edge of the giant Coma Cluster of Galaxies.

A Hurricane Over the South Pole of Saturn
13.11.2006

What's happening at the south pole of Saturn? To find out, scientists sent the robot Cassini probe now orbiting Saturn directly over the lower spin axis of the ringed giant. Cassini found there a spectacular massive swirling storm system with a well developed eye-wall, similar to a hurricane here on Earth.

LDN 1622: Dark Nebula in Orion
11.05.2007

The silhouette of an intriguing dark nebula inhabits this cosmic scene, based on images from the Palomar Observatory Sky Survey. Lynds' Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only easily seen in long telescopic exposures of the region.

Circum axial Leaf Trails
19.05.2007

Are photographs of star trails really evidence of the Earth's rotation about its axis? Yes they are, and science journalist Trudy E. Bell discovered that there is a simple way to demonstrate this, if you have the stomach for it.
