New observations by the Event Horizon Telescope have revealed a brightening of the jet only towards its edges - but for reasons that are currently unknown and an active topic of research.įollow HT Tech for the latest tech news and reviews, also keep up with us Todays NASA Astronomy Picture of the Day is a snapshot of Alpha Camelopardalis, a runaway star located about 4,000 light-years away in the long-necked constellation Camelopardalis. Filaments of the jet are visible in red in the upper left. This central black hole ejects a fast jet visible in both radio and X-ray light. Its active galactic nucleus harbors a supermassive black hole that is about 55 million times more massive than our Sun. The warped shape of Cen A is the result of a merger between an elliptical and a spiral galaxy. Cen A is the fifth brightest galaxy on the sky and is located at a distance of about 12 million light years from Earth. This is a classical 'butterfly'-shaped planetary nebula, with a dense equatorial. Pictured is NGC 5128, better known as Centaurus A. Astronomy Picture of the Day (APOD) is a website provided by NASA and Michigan Technological University (MTU). Hubble Space Telescope image of NGC 2346, whose nucleus is a 16 day binary. In galaxies, gravity alone holds together massive collections of stars, dust, interstellar gas, stellar remnants and dark matter. This glorious final phase in the life of a star. Discover how Hubble partners with the astronomy community COLLABORATING MISSIONS. In order, their catalog designations are NGC 1535, NGC 3242 (Ghost of Jupiter), NGC 6543 (Cat's Eye), NGC 7009 (Saturn Nebula), NGC 2438, NGC 6772, Abell 39, NGC 7139, NGC 6781, and M97 (Owl Nebula). Embark on a journey of discovery with the Hubble Space Telescope. It was discovered by Scottish astronomer James Dunlop in 1826 at Parramatta, in New South Wales, Australia. Ten different planetary nebula images are presented, each registered on the central star. According to NASA, Centaurus A is the closest active galaxy to Earth and is the result of the collision of two galaxies which caused star clusters and dark dust lanes to jumble up. This peculiar galaxy is located about 11 million light-years away towards the constellation of Centaurus and spans about 60,000 light-years across. Today's NASA Astronomy Picture of the Day is the elliptical galaxy NGC 5128, also known as Centaurus A. Most galaxies exist in groups or clusters with dozens or hundreds of members, and these cluster galaxies are all in constant motion, pulled and twisted by their neighbour's gravity. According to NASA, galaxies exist in huge groups which are closely connected by gravity. The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy. Stars, which illuminate the darkness of space, are formed in a giant cloud of dust and gas in space, known as a Nebula.
