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...
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...

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,...
Wolf-Rayet stars are known to be efficient dust producers, and the Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope shows this to great effect. Cooler cosmic dust glows at the longer mid-infrared wavelengths, displaying the structure of WR 124’s nebula. The nebula is made of...
NASA’s Roman Space Telescope will survey the same areas of the sky every few days following its launch in May 2027. Researchers will mine these data to identify kilonovae – explosions that happen when two neutron stars or a neutron star and a black hole collide and merge. When these collisions...
The galaxy JW100 features prominently in this image from the NASA/ESA Hubble Space Telescope, with streams of star-forming gas dripping from the disc of the galaxy like streaks of fresh paint. These tendrils of bright gas are formed by a process called ram pressure stripping, and their...
