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 [...]

Jupiter's Great Red Spot Is Shrinking—Now the Smallest Ever Seen

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


The Eighth Wonder: Happy 24th Birthday, Hubble (Part 1)

“If there were ever two missions that were completely opposite in terms of the public attention that was given to them,” astronaut Loren Shriver once [...]

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 [...]

Big Discovery: First Earth-Sized Exoplanet in Habitable Zone of Another Star

Today was another big day for those interested in space exploration and in the search for other Earth-like, alien worlds in particular: The first Earth-sized exoplanet orbiting another star in the habitable zone has been discovered, it was [...]

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 [...]
