A new planet, called PH3c, located 2,300 light years from Earth and has an atmosphere loaded with hydrogen and helium has been discovered by Yale astronomers and the Planet Hunters program. The elusive orb nearly avoided detection. This is because... Continue reading

NASA’s Hubble Space Telescope has picked up the faint, ghostly glow of stars ejected from ancient galaxies that were gravitationally ripped apart several billion years ago. The mayhem happened 4 billion light-years away, inside an immense collection of nearly 500... Continue reading

Earth is known as the Blue Planet because of its oceans, which cover more than 70 percent of the planet's surface and are home to the world's greatest diversity of life. While water is essential for life on the planet,... Continue reading

A team of planetary scientsts have compared their findings to data gathered from NASA’s planet-hunting Kepler Space Telescope and have concluded that the atmospheric mass of the planets Kepler found is, in some cases, far greater than the thin veneer... Continue reading

Australian physicists are challenging the foundations of quantum science with a new, and of course, unfalsifiable, theory based on the existence of, and interactions between, parallel universes. The team proposes that parallel universes really exist, and that they interact. That... Continue reading

Looking for radio signals (at least those used for communication) makes about as much sense as looking for evidence of telegraph poles on other planets. Considering many star systems out there may be millions (billions?) of years older than our... Continue reading

An Orbital Sciences rocket operating under a NASA contract exploded shortly after launch on Tuesday evening, much to everyone's surprise — except, perhaps, PayPal founder Elon Musk. Musk, today the the CEO of Tesla and SpaceX, trash-talked Orbital Sciences for... Continue reading

"Almost half the Sun-like stars were born in binary systems," says Emmanuel Di Folco with the Observatoire de Paris. "This means that we have found a mechanism to sustain planet formation that applies to a significant number of stars in... Continue reading

This ringed galaxy is actually a vast place of stellar life. Though galaxy NGC 1291 shown in this newly released image from NASA's Spitzer Space Telescope is quite old, roughly 12 billion years, it is marked by an unusual ring... Continue reading

Aeons ago, the universe was different: mergers of galaxies were common and gigantic black holes with masses equivalent to billions of times that of the Sun formed in their nuclei. As they captured the surrounding gas, these black holes emitted... Continue reading

“Exploration is in our nature. We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars," Carl Sagan, Cosmos.... Continue reading

The Planck satellite was launched in May 2009. With the highest accuracy to date, it measures the remnants of the radiation that filled the Universe immediately after the Big Bang. It is the oldest light in the Universe, emitted when... Continue reading

In the fall of 2012, astronomers using the NASA/ESA Hubble Space Telescope obtained a remarkable new view of a monster elliptical galaxy, with a core bigger than any seen before. Spanning a little over one million light-years, the galaxy is... Continue reading

Galaxy clusters are the largest objects in the universe, held together by gravity. These behemoths contain hundreds or thousands of individual galaxies that are immersed in gas with temperatures of millions of degrees. This hot gas, which is the heftiest... Continue reading

A large active region on the sun erupted with another X-class flare on Oct. 27, 2014 -- its fourth since Oct. 24. The flare peaked at 10:47 a.m. EDT. X-class denotes the most intense flares, while the number provides more... Continue reading

On Aug. 14, 2013, the Japanese amateur astronomer Koichi Itagaki discovered a "new" star that was subsequently named Nova Delphinus 2013. Now, astronomers have observed the expanding thermonuclear fireball from a nova that erupted last year in the constellation Delphinus... Continue reading

A fully developed elliptical galaxy is a gas-deficient gathering of ancient stars theorized to develop from the inside out, with a compact core marking its beginnings. This past August, for the first time, astronomers caught a glimpse of the earliest... Continue reading

Recently, a team of astronomers reported discovering a pulsating star that appears to shine with the energy of 10 million suns. The find, which was announced in Nature, is the brightest pulsar – a type of rotating neutron star that... Continue reading

Imagine: with a wasteland as their canvas, a Master and his young Apprentice set about turning rubble into planets and moons, asteroids and comets. They levitate the worlds above their heads, spinning them in orbit around their symbolic Sun. “What... Continue reading

"The idea that methane clouds could form this high on Titan is completely new," said Carrie Anderson, a Cassini participating scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study. "Nobody considered that possible... Continue reading

The moon passed between the Earth and the sun on Thursday, Oct. 23. While avid stargazers in North America looked up to watch the spectacle, the best vantage point was several hundred miles above the North Pole.The Hinode spacecraft was... Continue reading
China launched its first space mission to the moon and back early Friday, authorities said, the latest step forward for Beijing's ambitious program to one day land a Chinese citizen on the Earth's only natural satellite. The unnamed, unmanned probe... Continue reading

“Combined observations from small and large telescopes provide a unique opportunity to understand the nature of this complex and enigmatic triple asteroid system,” said Franck Marchis, senior research scientist at the Carl Sagan Center of the SETI Institute. “Thanks to... Continue reading

Once an object fall through the event horizon of a black hole, they’re lost forever. “It’s an exit door from our universe," said Shep Doeleman, assistant director at the MIT Haystack Observatory and research associate at the Smithsonian Astrophysical Observatory.... Continue reading

Almost 2,000 extrasolar planets have been discovered to date and this number is constantly increasing. Yet, we still know little about these alien worlds, especially their atmospheres. The atmospheres of terrestrial exoplanets could betray the presence of life on the... Continue reading
