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.

Hubble Discovers Two Potential KBO Targets for NASA's New Horizons Spacecraft, Follows Up With Additional Search

Discovery images of the two Kuiper Belt Objects named 1110113Y and 0720090F respectively, taken with NASA’s Hubble Space Telescope. The image at left shows the first KBO at an estimated distance of approximately 4 billion miles from Earth. Its position noticeably shifts between exposures taken approximately 10 minutes apart. The image at right shows […]

The Continuing Saga of Planet X: Could More Massive Planets Hide Beyond Pluto?

Just like the proverbial cat with nine lives, the notion of an unseen planet orbiting […]

From a Galaxy Far, Far Away: Astronomers Discover Ancient Super-Earths in Our Galactic Neighborhood

Artistic representation of the recently discovered, potentially habitable world Kapteyn b, with the globular cluster Omega Centauri in the background. It is believed that the Omega Centauri is the remaining core of a dwarf galaxy that merged with our own galaxy billions of years ago, bringing Kapteyn’s star along.

Colorful Hubble Image Provides Missing Link Concerning Star Formation

This composite image from the Hubble Space Telescope (HST) showing approximately 10,000 galaxies in brilliant color took nine years to assemble, and sheds light upon star formation in our Universe. Image Credit: NASA/ESA

NASA and the European Space Agency’s Hubble Space Telescope (HST) has done it again—this time, in brilliant color. A newly released […]

The Great Red Spot on Jupiter is one of the most recognizable features in the Solar System: a massive hurricane-like oval-shaped storm […]

Searching for Our Birthplace in the Galaxy: Astronomers Discover Potential Solar 'Sibling'

A visible image of the star HD 162826 (at right) in the constellation of Hercules, taken from the Digitized Sky Survey (DSS). A new study has identified the star as a being a solar sibling, thought to have been formed inside the same interstellar gas cloud that also gave birth to the Sun. Image […]

Buried in the Deep: Could Water Ice Deposits on the Moon Generate Their Own Organic Compounds?

A high-definition image of the Earth rising above the Moon’s south pole, taken from Japan’s Kaguya lunar orbiter in 2007. Permanently shadowed craters near the lunar polar regions have been found to harbor water ice deposits and organic compounds. Could these organics be composed in-situ inside the bottoms of these craters? Image Credit: JAXA
