Hunting In the Dark: New Results Come From Alpha Magnetic Spectrometer on ISS, But No Definite Signs of Dark Matter Yet

The Alpha Magnetic Spectrometer is seen here at center left, following its installation on the S3 Truss on the International Space Station by the crew of the STS-134 space shuttle mission in 2011. The orbiting particle detector has been continuously collecting data ever since, on high-energy cosmic rays. Image Credit: NASA

Living On the Edge: In the Realm of the Ice Giants (Part 5)

An artist’s concept of Neptune as seen from the surface of its largest moon Triton. Could this distant cold moon harbor an underground habitat for life in the outer reaches of the Solar System approximately 4.5 billion km from the Sun? Image Credit: Wikipedia

The universe is a wild and weird place, and two recent findings from orbiting space telescopes illustrate just how bewildering it can be: a monster-sized black hole in one of the tiniest galaxies known and a huge exoplanet that is [...]

Living On the Edge: The Mysterious Lakes of Titan (Part 4)

Titan’s colorful globe passes in front of Saturn and its rings, in this true color image taken in 2011 from NASA’s Cassini spacecraft. The moon’s opaque atmosphere hides a fascinating surface that is rich in methane lakes, water ice, and organic compounds. Image Credit: NASA/JPL-Caltech/Space Science Institute

“On Titan, the molecules that have [...]

Living On the Edge: The Icy Plains of Enceladus (Part 3)

Lit by reflected light from Saturn, Enceladus appears to hover above the gleaming rings with its well-defined ice particle jets spraying a continuous hail of tiny ice grains, in this image taken by NASA’s Cassini spacecraft in 2006 from a distance of 1.303 million kilometers. The 500-km-wide moon has excited the scientific community and [...]

They Came From Outer Space! The Mystery of the Fast Radio Bursts

Artist’s impression of a fast radio burst appearing in the sky above the 64-m Parkes Radio Telescope in Australia. A handful of these elusive cosmic radio flashes, whose exact origin remains unknown, have been detected during the last decade. Image Credit: CSIRO/Harvard/Swinburne Astronomy Productions

In 2007, David Narkevic, then a physics and political science [...]

Where's the Kaboom? Astronomers Detect No X-Ray Emission From Recent Supernova Explosion

The supernova SN 2014J, as imaged by NASA’s Chandra X-ray Observatory. This image contains Chandra data, where low-, medium-, and high-energy X-rays are red, green, and blue respectively. The boxes in the bottom of the image show close-up views of the region around the supernova in data taken prior to the explosion (left), as [...]

A Troubled Start to a Triumphant Mission: 37 Years Since the Launch of the Voyagers

Voyager 2 begins its journey of exploration, 37 years ago today (20 August), with a rousing liftoff atop a Titan IIIE-Centaur booster from Launch Complex (LC)-41 at Cape Canaveral. Photo Credit: NASA

A quarter-century ago, this week, NASA’s Voyager 2 spacecraft became the first machine fashioned by human hands to travel close to the [...]

Dust in the (Interstellar) Wind: Seven Particles of Possible Interstellar Origin Identified in Samples Returned by NASA's Stardust Spacecraft

A team of researchers has identified seven dust particles that were returned to Earth in 2006 by NASA’s Stardust spacecraft, which might have originated in the interstellar medium. This false-color image shows a diffraction pattern created by one of these particles, named Orion. Image Credit: Zack Gainsforth

Following a preliminary analysis of the dust [...]

The Improbable Case of the High-Energy Novae: NASA's Fermi Space Telescope Detects New Gamma Ray Sources

Novae typically originate in binary systems containing Sun-like stars, as shown in this artist’s rendering. NASA’s Fermi Space Telescope discovered that a nova in a system like this likely produces gamma rays (magenta) through collisions among multiple shock waves in the rapidly expanding shell of debris.
