Researchers Discover the First Exomoon Candidate

April 11, 2014

0 Comments

By using gravitational microlensing and taking advantage of chance alignments between stars, an international team of researchers has spotted the first signs of an exomoon. Titan, Europa, Io and Phobos are just a few members of our solar system’s pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun? NASA-funded […]

Curiosity Image Captures Mysterious Bright Spot

April 9, 2014

0 Comments

A newly released Curiosity image shows a bright spot on the surface of Mars, which was possibly caused by the sun glinting off a rock or cosmic rays striking the camera’s detector. Images taken by NASA’s Curiosity Mars rover on April 2 and April 3 include bright spots, which might be due to the sun […]

NASA Detects Ocean Inside Saturn’s Moon Enceladus

April 4, 2014

0 Comments

New data from NASA’s Cassini spacecraft and Deep Space Network provide the first geophysical measurements of the internal structure of Enceladus, suggesting that it harbors a large interior ocean beneath an ice shell. NASA’s Cassini spacecraft and Deep Space Network have uncovered evidence Saturn’s moon Enceladus harbors a large underground ocean of liquid water, furthering […]

New Data Helps Astronomers Piece Together the Evolution of Supermassive Black Holes

March 27, 2014

0 Comments

Using data from NASA’s Wide-field Infrared Survey Explorer, astronomers are piecing together the evolution of supermassive black holes. How do you grow a supermassive black hole that is a million to a billion times the mass of our sun? Astronomers do not know the answer, but a new study using data from NASA’s Wide-field Infrared […]

Cassini Views Four Moons of Saturn

March 25, 2014

0 Comments

Cassini views Saturn’s moons Prometheus, Pandora, Janus and Epimetheus. Two pairs of moons make a rare joint appearance. The F ring’s shepherd moons, Prometheus and Pandora, appear just inside and outside of the F ring (the thin faint ring furthest from Saturn). Meanwhile, farther from Saturn the co-orbital moons Janus (near the bottom) and Epimetheus […]

NASA’s Jet Propulsion Laboratory is developing a spacecraft, which looks like a giant sunflower, to acquire images of Earth-like rocky planets around nearby stars. This animation shows the prototype starshade, a giant structure designed to block the glare of stars so that future space telescopes can take pictures of planets.

Spitzer Images Create 360-Degree View of the Milky Way

March 21, 2014

0 Comments

Using more than 2 million infrared snapshots taken over the past 10 years by NASA’s Spitzer Space Telescope, researchers created a new 360-degree mosaic of the Milky Way. When you look up at the Milky Way on a clear, dark night, you’ll see a band of bright stars arching overhead. This is the plane of […]

NASA Image of the Day – Jupiter’s Great Red Spot Viewed by Voyager I

March 20, 2014

0 Comments

This NASA image of the day shows Jupiter’s Great Red Spot assembled from three black and white negatives from NASA’s Voyager 1. At about 89,000 miles in diameter, Jupiter could swallow 1,000 Earths. It is the largest planet in the solar system and perhaps the most majestic. Vibrant bands of clouds carried by winds that […]

WISE Survey Finds No Evidence of “Planet X”

March 10, 2014

0 Comments

Using data from NASA’s WISE exporter, two newly published studies reveal thousands of new stars, but no evidence of “planet X.” After searching hundreds of millions of objects across our sky, NASA’s Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed “Planet X.” […]

New Models Better Describe How Planet-Forming Material Around Stars is Stirred Up

March 7, 2014

0 Comments

Using data from NASA’s Spitzer Space Telescope, researchers have developed a new theory explaining the mystery of planet-forming disks that circle the young stars. Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006. Researchers using NASA’s Spitzer Space Telescope to study developing stars […]

NASA’s Cassini to Conduct Its 100th Flyby of the Saturn Moon Titan

March 6, 2014

0 Comments

NASA’s Cassini spacecraft is ready to conduct its 100th flyby of Titan. Ten years ago, we knew Titan as a fuzzy orange ball about the size of Mercury. We knew it had a nitrogen atmosphere — the only known world with a thick nitrogen atmosphere besides Earth. But what might lie beneath the hazy air […]

NASA’s NEOWISE Spacecraft Views Its First Comet

March 3, 2014

1 Comment

NASA’s NEOWISE spacecraft has spotted its first comet. Officially named “C/2014 C3 (NEOWISE),” the comet was about 143 million miles (230 million kilometers) from Earth at the time of discovery. NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft has spotted a never-before-seen comet — its first such discovery since coming out of hibernation late […]
