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

MESSENGER Completes 3,000 Orbits Around Mercury, Enters Final Year of Operations

An enchanced-color image of Mercury taken by MESSENGER, following its first flyby of the planet in January 2008. The spacecraft has recently entered its last year of operations, conducting more than 3,000 orbits around the planet, while transmitting more than 200,000 images back to Earth.

Contrary to the human need for organising objects in well-defined and distinct categories, our Solar System seems to be replete with celestial objects that defy our tidy definitions [...]

'Repairing Hubble' Showcases Space Telescope's Components on Anniversary

On Wednesday, April 23, Washington, D.C.’s Smithsonian National Air and Space Museum observed the 24th anniversary of NASA/ESA’s Hubble Space Telescope’s launch into orbit by unveiling “Repairing Hubble.” This new [...]

Studying the Light of Alien Atmospheres With NESSI

A new multi-object, near-infrared spectrograph, installed on the Magdalena Ridge Observatory’s 2.4-m Telescope, will study the atmospheres of extrasolar planets located relatively close to Earth, allowing astronomers to probe their chemical composition. Image Credit: MRO

Exoplanetary astronomy has been one of the most productive scientific endeavors in recent years, with new discoveries of planets [...]

A Light in the Dark? Observations of Milky Way's Center Hint at Existence of Dark Matter

A view of the entire gamma-ray sky from the Fermi Space Telescope, shaded to emphasize the center of the Milky Way. The inset is a map of the galactic center with known sources removed, which reveals the gamma-ray excess (red, green, and blue) found there. This excess emission is consistent with annihilations from some [...]

First Direct Imaging of Exoplanet in Visible Light Obtained by Ground-Based Telescope

Image of the exoplanet Beta Pictoris b made with the Magellan Adaptive Optics (MagAO) VisAO camera. This image was made using a CCD camera, which is essentially the same technology as a cell phone camera. The planet is nearly 100,000 times fainter than its star and orbits its star at roughly the same distance [...]

Listening to the Cosmic Winds, Then Talking to the Artist Who Recorded Them

NASA’s Voyager missions are part of humanity’s greatest achievements ever, inspiring the generations. Their tremendous collection of scientific data have also inspired a scientist/musician who converted them into music, giving a whole new meaning and appreciation to both science and music.

“The heavenly motions… are nothing but a continuous [...]

New Dwarf Planet Candidate Discovered at Solar System's Edge: Could a Hidden Planet Be Orbiting Farther Out?

The discovery images of 2012 VP113. Three images of the night sky, each taken about two hours apart, were combined into one. The first image was artificially colored red, the second green, and the third blue. 2012 VP113 moved between each image as seen by the red, green, and blue dots. The background stars [...]

Probing the Surfaces of Alien Waters: Cassini Reveals Possible Evidence of Waves on Seas of Titan

An image of Kivu Lacus, a small lake on Titan’s northern hemisphere, taken in infrared wavelengths in July 2012 with Cassini’s VIMS instrument from a distance of approximately 30,000 km. The bright spot indicates a specular reflection of sunlight from the surface of Kivu Lacus, which could result from the formation of waves. Image [...]
