The Necklace Nebula is located 15,000 light-years away in the constellation Sagitta (the Arrow). New image, taken on July 2, 2011, Hubble’s Wide Field Camera 3 shows the glow of hydrogen (blue), oxygen (green), and nitrogen (red). The Necklace Nebula, is a recently discovered planetary nebula, the glowing remains of an ordinary, Sun like star.
Nix and Hydra, that are the Pluto’s small moons was discovered by astronomers using NASA’s Hubble Space Telescope,in 2005.The two moons are nearly 5,000 times fainter than Pluto and are about two to three times farther from Pluto than its large moon, Charon.Nix is dimmer and smaller than Hydra. Astronomers think that both moons are smaller than 50 miles (80 km) in diameter.
Scientists can take a new image of the galaxy Centaurus A using NASA’s Hubble Space Telescope (June 16, 2011), with the help of which they can reveals never before seen details of its. The image show features in the visible, ultraviolet and near-infrared spectrum.At a distance of just over 11 million light-years, Centaurus A contains the closest active galactic nucleus to Earth.
With the help NASA’s Dawn spacecraft , astronomers can receive 20 new images of Vesta asteroid, on June 1. The images show a dark feature near Vesta’s equator moving from left to right across the field of view as Vesta rotates. They also show Vesta’s jagged, irregular form , hinting at the enormous crater known to exist at Vesta’s south pole.
The new NASA’s Hubble Space Telescope image (June 10) shows the closest supernova explosion, called Supernova 1987A, witnessed in almost 400 years, which has allowed astronomers to study it in unprecedented detail as the outburst evolves.In the new Hubble image, SN 1987A is surrounded by a ring of material that blew off the star thousands of years before it exploded.
Astrophysics at Oxford University reconstructed the collision of galaxies, which led to the emergence of system Arp 147, located about four hundred and thirty million light-years from Earth in the constellation of Cetus.System Arp 147 is a “Galactic Pair, consisting of two objects ring-shaped and elliptical galaxies.
In elliptical galaxies, all stars were formed billions of years ago, and there are no gas from which could be produced new stars, so it was thought that their star formation stopped. Because of that scientists believed that they was “dead” galaxies, which stopped doing the star for a long time
A new photo by NASA Hubble Space Telescope shows the spiral galaxy NGC 5775 surrounded by a halo of gas Astronomers think that this gas was created by star explosions like a galaxy size fountain
NASA and the European Space Agency’s Hubble Space Telescope, and the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile take images the Lopsided Galaxy called “Meathook”, or NGC 2442.
