BEST AND LATEST SPACE RESEARCH 2

Using NASA’s Chandra X-ray Observatory, scientists have created a stunning new image of one of the youngest supernova remnants in the galaxy. This new view provided by NASA shows the debris of an exploded star that helps astronomers solve a long-standing mystery, with implications for understanding how a star’s life can end catastrophically and for gauging the expansion of the universe. Chandra’s latest image marks a new phase in understanding the object now known as Kepler’s supernova remnant. By combining nearly nine days of Chandra observations, astronomers have generated an X-ray image with unprecedented detail of one of the brightest recorded supernovas in the Milky Way galaxy.

This image provided by NASA’s Hubble Space Telescope shows the galaxy Zwicky 18. NASAs Hubble Space Telescope has found the galaxy is the equivalent of the painting of Dorian Gray, a portrait in an Oscar Wilde novel that appears mysteriously to age. Like the fictional painting, the galaxy I Zwicky 18 appears to look older the more astronomers study it. New Hubble data have quashed that possibility. The telescope found faint older stars contained within the galaxy, suggesting its star formation started at least one billion years ago and possibly as much as 10 billion years ago. The galaxy, therefore, may have formed at the same time as most other galaxies. Although the galaxy is not as youthful as was once believed, it is certainly developmentally challenged and unique in the nearby universe, said astronomer Alessandra Aloisi from the Space Telescope Science Institute and the European Space Agency in Baltimore, Md., who led the new study.

This image provided by NASA shows the striking Maunder crater lying at approximately 50 degrees South and 2 degree East, in the Noachis Terra region on Mars. The High Resolution Stereo Camera (HRSC) on ESA’s Mars Express orbiter took pictures of the Noachis Terra region during orbits 2412, with a ground resolution of approximately 15 metres per pixel. The sun illuminates the scene from the north-east (top left in the image). Maunder crater, named after the british astronomer Edward W. Maunder, is located halfway between Argyre Planitia and Hellas Planitia on the southern highlands of Mars.

In this image provided by NASA shows the very deep image taken with the NASA/ESA Hubble Space Telescope shows the spiral galaxy NGC-4921 along with a spectacular backdrop of more distant galaxies. It was created from a total of 80 separate pictures through yellow and near-infrared filters.
