NASA released Thursday an image of a comet that, on Oct. 19, will pass within [...]
This illustration shows the unusual orbit of planet Kepler-413b around a close pair of orange and red dwarf stars. The planet’s 66-day orbit is tilted 2.5 degrees with respect to the plane of the binary star’s orbit. The orbit of the planet wobbles around the central stars over 11 years, an effect called precession. [...]

WASHINGTON — Astronomers have used NASA’s Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory’s launch aboard the Space Shuttle Discovery on April 24, 1990.
This artist’s concept depicts a dense, dead star called a white dwarf crossing in front of a small, red star. The white dwarf”s gravity is so great it bends and magnifies light from the red star. Image credit: NASA/JPL-Caltech
NASA’s Kepler space telescope has witnessed the effects of a dead star bending the light [...]
Since its inaugural deployment from the shuttle in April 1990, the Hubble Space Telescope has peered deeper into the cosmos than ever before in human history. The recent discovery of Supernova SN Wilson—more than 10 billion years old—refines scientists’ yardstick for the age of the Universe. Photo Credit: NASA
More than two decades since [...]

PASADENA, Calif — Two of NASA’s great observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a strobe light.
The newly discovered galaxy, named MACS0647-JD, is very young and only a tiny fraction of the size of our Milky Way. The object is observed 420 million years after the big bang. The inset at left shows a close-up of the young dwarf galaxy. This image is a composite taken with Hubble’s WFC 3 [...]

Asteroid belts similar to the one around the Sun, but not ones that are much sparser or denser, might be crucial to the appearance of life on [...]
