Topic: InfraredWritten by Dr. Tony Phillips
Many galaxies, perhaps all, contain such a “monster in the middle.” These supermassive black holes sustain themselves by swallowing stars, planets, asteroids, comets and clouds of gas that wander by the crowded galactic core. NASA’s NuSTAR spacecraft recently caught the Milky Way’s central black hole in the act of having a snack. «Read the rest of this article» Sections: News | No Comments
NASA Satellites monitor Hurricane SandyWritten by Alan Buis
NASA’s Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua spacecraft captured this infrared image of Hurricane Sandy at 2:17pm EDT on October 29th, 2012. ![]() NASA’s Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua spacecraft captured this infrared image of Hurricane Sandy, another weather front to the west and cold air coming down from Canada at 2:17pm EDT Oct. 29th. The hurricane center is the darkest purple area in the Atlantic just to the east of the New Jersey coast, reflecting Sandy’s areas of heaviest rainfall.

NASA’s Mars rover Curiosity for the first time uses it’s Laser to analyze a Rock on MarsWritten by Guy Webster and D.C. Agle
The mission’s Chemistry and Camera instrument, or ChemCam, hit the fist-sized rock with 30 pulses of its laser during a 10-second period. Each pulse delivers more than a million watts of power for about five one-billionths of a second. ![]() This composite image, with magnified insets, depicts the first laser test by the Chemistry and Camera, or ChemCam, instrument aboard NASA’s Curiosity Mars rover.

NASA’s Wide-field Infrared Survey Explorer takes image of Flame Nebula in the Constellation OrionWritten by Whitney Clavin
The image is being released along with a new batch of data from the mission. Last March, WISE released its all-sky catalog and atlas containing infrared images and data on more than a half billion objects, including everything from asteroids to stars and galaxies. Now, the mission is offering up additional data from its second scan of the sky. ![]() The Flame Nebula sits on the eastern hip of Orion the Hunter, a constellation most easily visible in the northern hemisphere during winter evenings.

NASA’s Spitzer Space Telescope finds Patterns of Light from First Objects in the UniverseWritten by Whitney Clavin
They are too far away to be seen individually, but Spitzer has captured new, convincing evidence of what appears to be the collective pattern of their infrared light. The observations help confirm the first objects were numerous in quantity and furiously burned cosmic fuel. ![]() Astronomers have uncovered patterns of light that appear to be from the first stars and galaxies that formed in the universe. The light patterns were hidden within a strip of sky observed by NASA's Spitzer Space Telescope.

NASA’s Hubble Space Telescope spots Searchlight Beams from Preplanetary NebulaNASA’s Goddard Space Flight Center
One stage that stars pass through as they run out of nuclear fuel is called the preplanetary or protoplanetary nebula stage. This Hubble image of the Egg Nebula shows one of the best views to date of this brief but dramatic phase in a star’s life. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Hubble Space Telescope peeks inside the Large Magellanic CloudNASA’s Goddard Space Flight Center
The stellar grouping is known to stargazers as NGC 2040 or LH 88. It is essentially a very loose star cluster whose stars have a common origin and are drifting together through space. ![]() Large star formation in the Large Megellanic Cloud.

Herschel Space Observatory looks into the Dark Heart of a Cosmic CollisionWritten by Whitney Clavin
The infrared light was captured by the European Space Agency’s Herschel Space Observatory, a mission with important NASA contributions. The X-ray observations were made by the European Space Agency’s XMM-Newton space telescope. ![]() The peculiar galaxy Centaurus A as seen in longer infrared wavelengths and X-rays. Inner structural features seen in this image are helping scientists to understand the mechanisms and interactions within the galaxy, as are the jets seen extending over thousands of light years from the black hole believed to be at its heart.

NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) Captures Image of Dying, Outflowing StarWritten by Whitney Clavin
The object observed by SOFIA, planetary nebula Minkowski 2-9, or M2-9 for short, is seen in this three-color composite image. ![]() NASA's SOFIA telescope and the FORCAST instrument captured this color-composite image of the planetary nebula Minkowski 2-9 (M2-9) showing a dying sun-like star.

NASA’s Hubble Space Telescope Discovers Waterworld PlanetHarvard-Smithsonian Center for Astrophysics
“GJ 1214b is like no planet we know of,” Berta said. “A huge fraction of its mass is made up of water.” The ground-based MEarth Project, led by CfA’s David Charbonneau, discovered GJ 1214b in 2009. This super-Earth is about 2.7 times Earth’s diameter and weighs almost seven times as much. It orbits a red-dwarf star every 38 hours at a distance of 2 million kilometres, giving it an estimated temperature of 230 degrees Celsius. ![]() GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. GJ1214b represents a new type of planet, like nothing seen in our solar system or any other planetary system currently known. It’s smaller than Uranus but larger than Earth.
