Astronomers Find Giant Planet Around Very Young Star

116420_web.jpg

In contradiction to the long-standing idea that larger planets take longer to form, U.S. astronomers today announced the discovery of a giant planet in close orbit around a star so young that it still retains a disk of circumstellar gas and dust.

Astronomers Confirm Faintest Early-Universe Galaxy Ever Seen

116187_web.jpg

An international team of scientists, including two professors and three graduate students from UCLA, has detected and confirmed the faintest early-universe galaxy ever. Using the W. M. Keck Observatory on the summit on Mauna Kea in Hawaii, the researchers detected the galaxy as it was 13 billion years ago. The results were published in the Astrophysical Journal Letters.

On May 12, 2016, astronomers using NASA's Hubble Space Telescope captured this striking image of Mars, when the planet was 50 million miles from Earth. The photo reveals details as small as 20 miles to 30 miles across. This observation was made just a few days before Mars opposition on May 22, when the sun and Mars will be on exact opposite sides of Earth, and Mars will be 47 million miles from Earth.

Ancient Tsunami Evidence on Mars Reveals Life Potential

TsunamisMarsPhoto.jpg

The geologic shape of what were once shorelines through Mars’ northern plains convinces scientists that two large meteorites – hitting the planet millions of years apart – triggered a pair of mega-tsunamis. These gigantic waves forever scarred the Martian landscape and yielded evidence of cold, salty oceans conducive to sustaining life.

Squeezing Out Mountains, Mathematically, on Jupiter’s Moon Io

021206_Galileo_Io_at_sunset.jpg

Mountains aren’t the first thing that hit you when you look at images of Jupiter’s innermost moon, Io. But once you absorb the fact that the moon is slathered in sulfurous lava erupted from 400 active volcanoes, you might turn your attention to scattered bumps and lumps that turn out, on closer inspection, to be Io’s version of mountains.

Hunting for Hidden Life on Worlds Orbiting Old, Red Stars

All throughout the universe, there are stars in varying phases and ages. Planetary diversity suggests that around other stars, initially frozen worlds could be the size of Earth and provide habitable conditions once the star becomes older. The oldest detected Kepler planets (exoplanets found using NASA’s Kepler telescope) are about 11 billion years old. Our sun is currently 4.6 billion years old. Astronomers usually looked at middle-aged stars like our sun, but to find habitable worlds, one needs to look around to stars of all ages, including red giants.
