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.

ESA's 'Discovery Machine' Gets Ready for Science: Gaia Concludes Commissioning Phase, Begins Primary Five-Year Mission

Artist’s concept of the Gaia. Having recently completed a rigorous test and commissioning phase, the space observatory began its five-year primary science mission of mapping and cataloguing approximately 1 billion stars in the Milky Way galaxy. Image Credit: ESA–D. Ducros, 2013

Following the successful conclusion of a very demanding and extensive six-month commissioning period, [...]

To Navigate the Seas of the Sun: NASA's Solar Probe Plus Mission to the Nearest Star

Artist’s impression of NASA’s Solar Probe Plus spacecraft approaching the Sun. Set to launch in 2018, Solar Probe Plus will orbit our home star a total of 24 times while gradually approaching closer with each concecutive orbit, until it eventually achieves a minimum distance of 8.5 solar radii, or 3.7 million miles from the [...]

Exploring Uncharted Territory: ESA's Venus Express Spacecraft Completes Aerobraking Campaign, Raises Orbit Prior to End of Mission

An artist’s concept of Venus Express during the aerobraking manoeuvre, which saw the spacecraft orbiting Venus at an altitude of approximately 130 km from 18 June to 11 July. These low passes through the atmosphere of Venus allowed the spacecraft to conduct scientific observations that weren’t possible from higher altitudes. Image Credit: ESA–C. Carreau

No Water, Please: The Case of the Surprisingly Dry 'Hot Jupiters'

This is an artistic illustration of the gas giant planet HD 209458b in the constellation Pegasus. The planet was recently studied by astronomers alongside two other similar extrasolar worlds, for their abundance in water. To the surprise of astronomers, they have found much less water vapor in the planets’ atmospheres than standard planet-formation models [...]

Astronomers Discover First Ice Giant Exoplanet Candidate in Long-Period Orbit

This artist’s concept shows Kepler-421b, a Uranus-sized transiting exoplanet with the longest known year, circling its star once every 704 days. Kepler-421b orbits an orange, K-type star that is cooler and dimmer than our Sun and is located about 1,000 light-years from Earth in the constellation Lyra.
