This image was created on March 31, 2005, from data gathered by NASA’s Hubble Space Telescope and shows dust lanes and star clusters in this giant galaxy. Astronomers say these characteristics give a clue as to how this galaxy was formed. This image was featured as our , Meglepően összetett hurkok és csöppje kozmikus pornak fekszik rejt, Az első galaxis, [kep]http://a52.g.akamaitech.net/f/52/827/1d/www.space.com/images/besthubble_deep_field_02.jpg[/kep], Hubble’s Ultra Deep Field, Astronomers at the Space Telescope Science Institute, on March 9, 2004, unveiled the deepest portrait of the visible universe ever achieved by humankind. Called the Hubble Ultra Deep Field (HUDF), the million-second-long exposure revea, Saturn's Moon Helene from Cass, of the diminutive moon. Although conventional craters and hills appear, the above raw and unprocessed image also shows terrain that appears unusually smooth and streaked. Planetary astronomers will be inspecting these detailed images of Helene to glean clues about the origin and evolution of the 30-km across floating iceberg. Helene is also unusual because it circles Saturn just a, The Center of Centaurus A, billion times the mass of the Sun! Centaurus A itself is apparently the result of a collision of two galaxies and the left over debris is steadily being consumed by the black hole. Astronomers believe that such black hole central engines generate the radio, X-ray, and gamma-ray energy radiated by Centaurus A and other active galaxies. But for an active galaxy Centaurus A is close,, The Necklace Nebula, central star, near the center of a ring strongly tilted to our line of sight, has also been shown to be binary, a close system of two stars with an orbital period of just over a day. Astronomers estimating the apparent age of the ring to be around 5,000 years, also find more distant gas clouds perpendicular to the ring plane, seen here at the upper left and lower right. Those clou, Mirach's Ghost , Mirach's Ghost , Explanation: As far as ghosts go, Mirach's Ghost isn't really that scary. In fact, Mirach's Ghost is just a faint, fuzzy galaxy, well known to astronomers, that happens to be seen nearly along the line-of-sight to Mirach, a bright star. Centered in this star field, Mirach is also called Beta Andromedae. About 200 light-years distant, Mirach is a red giant, Our Solar System:, of scale and size., [kep]http://solarsystem.nasa.gov/images/OSS_708.jpg[/kep], From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. They called these objects planets, meaning wanderers, and named them after Roman deities - Jupiter, king of the gods; Mars, t, Dwarf Planets, planets Eris, Pluto and Ceres in comparison to Earth. Pluto's moon Charon also is shown., , What is a planet? We've been asking that question at least since Greek astronomers came up with the word to describe the bright points of light that seemed to wander among fixed stars. Our solar system's planet count has soared as high as 15 before it was decided that , Beyond Our Solar System, in our galaxy. So far we know almost 400 of them have planets in their orbits., , Before 1991, the worlds of our own solar system were the only known planets. Astronomers did not believe that our sun's environment was the only planet producer in the universe. But they had no evidence of planets outside our solar system., How quickly things change., Our Solar System, of our solar system with separate representations of scale and size., , From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. They called these objects planets, meaning wanderers, and named them after Roman deities - Jupiter, king of the gods; Mars, Bright Supernova, right is SN 2006gy. The panel to the right shows Chandra's X-ray image of the same field of view, again showing the nucleus of NGC 1260 and SN 2006gy. The Chandra observation allowed astronomers to determine that SN 2006gy was indeed caused by the collapse of an extremely massive star, and not the most likely alternative explanation for the explosion, the destruction of a low-mass, Rotating Vesta Astronomers com, Rotating Vesta, Astronomers combined 146 exposures taken by NASA's Hubble Space Telescope to make this 73-frame movie of the asteroid Vesta's rotation. Vesta completes a rotation every 5.34 hours., [kep]http://solarsystem.nasa.gov/multimedia/gallery/Vesta_br1.jpg[/kep], New Spin on Vesta , Chris Russell, principal investigator for NASA's Dawn mission, explains, Astronomy Picture of the Day, Croman, Explanation: Big beautiful spiral galaxy M66 lies a mere 35 million light-years away. About 100 thousand light-years across, the gorgeous island universe is well known to astronomers as a member of the Leo Triplet of galaxies. In M66, pronounced dust lanes and young, blue star clusters sweep along spiral arms dotted with the tell-tale glow of pink star forming regions., Great Supernova in 1987 , the Hubble Space Telescope, in, Újabb "sebhely" keletkezett a Jupiteren, aki Naprendszerünk legnagyobb bolygóját figyelte meg épp a becsapódáskor - olvasható a Space.com űrkutatási hírportálon (http://www.space.com/17534-jupiter-impact-explosion-amateur-astronomers.html)., "Mindössze 1,5-2 másodpercig tartott a fényes felvillanás" - magyarázta az amerikai amatőrcsillagász, hozzátéve: kezdetben nem lehetett tudni, hogy a becsapódás ugyanúgy "sebet e, A legmasszívabb fekete lyukat mérték meg amerikai csillagászok, teleszkópjával, a masszív galaxisfelmérési program (MGS/ Massive Galaxy Survey) keretében végezték a vizsgálatokat - olvasható a PhysOrg tudományos hírportálon (http://phys.org/news/2012-11-astronomers-massive-unusual-black-hole.html)., A projekt során figyeltek fel a 220 millió fényévnyire, a Perszeusz-csillagképben lévő NGC 1277 katalógusjelű csillagvárosra.
