A spectacular landscape of star formation

This image, captured by the Wide Field Imager at the European Southern Observatory’s (ESO) La Silla Observatory in Chile, shows two dramatic star formation regions in the southern Milky Way. The first of these, on the left, is dominated by the ...

First LOFAR observations of the Whirlpool Galaxy

Using a radio telescope with frequencies just above those of commercial FM radio stations, a European team of astronomers has obtained the most sensitive image of a galaxy below 1 gigahertz. The team viewed the Whirlpool Galaxy (M51), about 30 milli...

Fascinating rhythm: light pulses illuminate a rare black hole

The universe has so many black holes that it’s impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big or colossal. Astronomers know...

As seen by Rosetta: comet surface variations

A new image of Comet 67P/Churyumov-Gerasimenko shows the diversity of surface structures on the comet's nucleus. It was taken by the Rosetta spacecraft's OSIRIS narrow-angle camera on August 7, 2014. At the time, the spacecraft was 65 miles (104km) a...

Stardust team reports discovery of first potential interstellar space particles

Seven rare microscopic interstellar dust particles that date to the beginnings of the solar system are among the samples collected by scientists who have been studying the payload from NASA’s Stardust spacecraft since its return to Earth in 200...

Chandra Observatory searches for trigger of nearby supernova

New data from NASA’s Chandra X-ray Observatory offer a glimpse into the environment of a star before it exploded earlier this year and insight into what triggered one of the closest supernovae witnessed in decades. The data gathered on the Jan...

Hubble revisits a globular cluster’s age

This new NASA/ESA Hubble Space Telescope image shows the globular cluster IC 4499. Globular clusters are big balls of old stars that orbit around their host galaxy. It has long been believed that all the stars within a globular cluster form at the a...

Tall boulder rolls down martian hill, lands upright

A track about one-third of a mile (500 meters) long on Mars shows where an irregularly shaped boulder careened downhill to its current upright position as seen in a July 3, 2014, image from the High Resolution Imaging Science Experiment (HiRISE) came...

NuSTAR sees rare blurring of black hole light

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the black hole, called the corona, has move...

Cassini tracks clouds developing over a Titan sea

NASA’s Cassini spacecraft recently captured images of clouds moving across the northern hydrocarbon seas of Saturn’s moon Titan. This renewed weather activity, considered overdue by researchers, could finally signal the onset of summer st...

Pinwheel Galaxy snapped by VST

The VLT Survey Telescope (VST) at the European Southern Observatory’s (ESO) Paranal Observatory in Chile has captured a beautifully detailed image of galaxy Messier 33 (M33). This nearby spiral, the second closest large galaxy to the Milky Way,...

Astronomers find stream of gas — 2.6 million light-years long

Astronomers and students have found a bridge of atomic hydrogen gas 2.6 million light-years long between galaxies 500 million light-years away. They detected the gas using the William E. Gordon Telescope at the Arecibo Observatory, a radio astronomy ...
