Airships are a unique form of transportation—giant, balloon-like, lighter-than-air vehicles which can stay aloft for extended periods of time. Their design makes them […]

Intergalactic Space Is Brighter Than Thought, NASA Rocket Experiment Shows

The universe is vast and, apart from the stars and galaxies, a seemingly very dark and empty place, with utter blackness […]

Bizarre Universe: Massive Black Hole In Tiny Galaxy and Exoplanet That Makes Its Star Act Older Than It Is

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 […]

Astronomers Witness Asteroid Smash-Up Around Sun-Like Star

Solar systems, including ours, are thought to begin as massive clouds of dust and gas surrounding young stars; over billions of years, planets form from repeated impacts of […]

Astronomers Observe the Rhythm of Rare Type of Black Hole

Black holes are one of the most unusual and fascinating phenomena in nature, and now astronomers are learning more about a peculiar type of black hole, thanks to archived data from NASA’s Rossi […]

NASA's X-Ray Space Telescope Celebrates 15 Years

Astronomers on Monday made a “big” announcement about exoplanets, and it is big—literally. Another new world has been discovered, which is quite routine now these days, but this one is different, and unexpected: a planet which is more than twice as large […]

Hazy Sunsets on Titan Provide Clues to Atmospheres on Alien Exoplanets

Saturn’s moon Titan is one of the murkiest places in the Solar System; its thick smog-like hydrocarbon haze in the upper atmosphere shrouds the entire moon, much like Venus’ perpetual cloud […]

Kepler Phase 2: Planet-Hunting Space Telescope's New Mission Proposal Approved

There is some good news for planet-hunters this week: The proposed K2 mission extension for the Kepler Space Telescope has been been approved by NASA. The approval, based on a recommendation from […]

Big Discovery: First Earth-Sized Exoplanet in Habitable Zone of Another Star
