Watch four alien worlds orbit a distant star

Keck telescope in Hawaii C. Marois et al., NRC Canada A K-band AO image of the HR 8799 planetary system made using Gemini/Altair/NIRI . Observations have shown counterclockwise Keplerian orbital motion for all three planets.

V* V342 Peg, also known as HR 8799, has a mass about 1.5 times that of our own Sun. Keck telescope in Hawaii captured in infrared light three planets orbiting an artificially obscured central star.Each planet likely contains several times the mass of Jupiter, but even the innermost planet, labelled d, has an orbital radius near the equivalent of the Sun- Neptune distance.

Emission Nebula IC 417.is an emission nebula that is energized by embedded hot, massive blue stars. The bluish clouds of gas at the top of the image are locations of new star formation. The image was generated with observations in the B (blue), I (orange) and Hydrogen-Alpha (red) filters. In this image, North is left, East is down.

Informally known as the spider, IC 417 is an emission nebula that is energized by embedded hot, massive blue stars. The bluish clouds of gas at the top of the image are locations of new star formation.

Comet Pan-STARRS (C/2011 L4), widely expected to become a naked-eye object in early March, is now closer to the sun than Venus.

LAS VEGAS (AP) — NASA is partnering with a commercial space company in a bid to replace the cumbersome "metal cans" that now serve as astronauts' homes in space with inflatable bounce-house-like habitats that can be deployed on the cheap.

Fotografían el embrión de la estrella más masiva de la Vía Láctea

Observations of the dark cloud SDC using the Atacama Large Millimeter/submillimeter array (ALMA) have given astronomers the best view yet of a monster star in the process of forming.
