Hubble photographs playful galactic duo

Hubble photographs playful galactic duo

Science
Aug. 9 (UPI) -- NASA shared an image, recently captured by Hubble, of the galactic duo UGC 2369 on Friday. The image showcases the pair caught in a playful dance. Long, long ago, the galaxies were separate, but today, they are in the midst of colliding. Slowly, their mutual gravitational attraction is pulling them closer and closer. As they've become entwined, gravity has distorted their features, altering their appearances. "A tenuous bridge of gas, dust and stars can be seen connecting the two galaxies, created when they pulled material out into space across the diminishing divide between them," NASA wrote in a news release. Still, despite their contortions and shared name, the two galactic entities remain visibly distinct. Millions of years from now, however, the pair will be almost c...

Exoplanet-hunting CubeSat photographs Los Angeles

Science
May 17 (UPI) -- NASA's smallest exoplanet-hunting satellite, the CubeSat ASTERIA, recently captured photographs of Los Angeles from 250 miles above Earth's surface. The space agency's Jet Propulsion Laboratory published the photographs on its website this week. ASTERIA, short for Arcsecond Space Telescope Enabling Research in Astrophysics, is a miniaturized satellite made up of six cubed units measuring 4.5 inches on each size. Most of the time, ASTERIA is pointed away from Earth, searching for alien worlds in the Milky Way, far beyond our own solar system. But in March, the CubeSat trained its camera on the City of Angels. The newly published photos reveal Los Angeles' grid of city streets and freeways -- lots and lots of freeways -- glowing in the night. On the evening that ASTERIA sna...

March 8 (UPI) -- Millions of galaxies across the universe are colliding right now. Two of them can be seen in a new Hubble image. Unlike a car crash, asteroid strike or planetary smashup, all of which happen quickly, galactic collisions play out over millions of years. The drawn-out nature of the drama offers astronomers and their telescopes -- on the ground and in space -- plenty of time to document the cosmic phenomena. Many galactic collisions are named as a single entity. Astronomers named the duo in the new Hubble image NGC 6052. When William Herschel first spotted NGC 6052 in 1784, he and his fellow astronomers classified the object as a single irregular galaxy. Scientists now know NGC 6052 is not one oddly shaped galaxy, but two galaxies -- each warped by the gravity and momentum ...

Tiny X-ray beam reveals hidden photographs from the 19th century

June 22 (UPI) -- Scientists have successfully recovered images from some of the earliest daguerreotypes, the silver plates used for one of the earliest forms of photography. To the naked eye, the portraits of a man and woman are unrecognizable. The daguerreotypes, taken as early as 1850, are too degraded by tarnish and wear. But researchers used rapid-scanning micro-X-ray fluorescence to see past the deterioration and recover the early images. "It's somewhat haunting because they are anonymous and yet it is striking at the same time," Madalena Kozachuk, a PhD student in the chemistry department at the University of Western Ontario, said in a news release. The images were analyzed at the National Gallery of Canada's photography research unit, where the daguerreotypes are stored. "The imag...
