‘Taffy Galaxies’ Collide, Leave Behind Bridge of Star-Forming Material
The Gemini North telescope, one half of the International Gemini Observatory, operated by NSF’s NOIRLab, captured this dazzling image of the so-called Taffy Galaxies — UGC 12914 and UGC 12915. Their twisted appearance is the result of a head-on collision that occurred about 25 million years...
Spiderweb Galaxy
The Sunyaev-Zeldovich effect in the Spiderweb protocluster
This image shows the protocluster around the Spiderweb galaxy (formally known as MRC 1138-262), seen at a time when the Universe was only 3 billion years old. Most of the mass in the protocluster does not reside in the galaxies that can be seen in the centre of the image, but in the gas known...

Globular Cluster Omega Centauri Captured by NEWFIRM on the Blanco Telescope
During its commissioning and capabilities testing, astronomers used NEWFIRM on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO) in Chile to capture a spectacular image of the Omega Centauri globular cluster. At about 17,000 light-years from Earth in the...
Everything, in one place, all at once
This luminous Picture of the Week shows Z 229-15 — imaged here in beautiful detail by the NASA/ESA Hubble Space Telescope — a celestial object that lies about 390 million light-years from Earth in the constellation Lyra. Z 229-15 is one of those interesting celestial objects that, should you...

Hubble Monitors Changing Weather and Seasons on Jupiter and Uranus
Ever since its launch in 1990, NASA’s Hubble Space Telescope has been an interplanetary weather observer for keeping an eye on the largely gaseous outer planets, which all have ever-changing atmospheres. NASA spacecraft missions to the outer planets have given us a close-up look at these...

IC4701
Plunge into a stellar ocean
In this Picture of the Week, we take a deep plunge into the ocean of stars in the IC4701 nebula. This nebula is located in the Sagittarius constellation, and it is twice as wide as the full Moon in the sky. The energetic light from newly-born stars ionizes the hydrogen gas in the nebula,...
