... Credit: P. Garnavich ( CfA ), High-z Supernova Search Team, NASA Explanation: Watching galaxies recede , observational astronomers of the 20th century discovered an astounding fact - the Universe is expanding. ... As recently reported , the apparent brightness and expansion velocities associated with these and other distant supernovae are beginning to suggest that the expansion rate of the Universe has not slowed but increased over time and that the expansion of the Universe is destined to continue....

... Most people that are interested in supernovae use whatever telescopes they can get access to, but researchers at certain colleges and universities are able to access specialized telescopes like NASA?s Chandra X-ray Observatory . It?s a telescope that orbits the Earth and that has a specialized purpose of being able to observe X-ray emissions from supernovae, clustered galaxies and the materials around black holes. ... super@supernovae.net . ...

To locate it, look along the imaginary line between the two end stars on the leading edge of the Plough���s blade (Merak and Dubhe) and Polaris (the North Star), the galaxy M82 (also known as the Cigar Galaxy) along with its companion M81, lies just off this line about a third of the way between the Plough and Polaris. ����As usual, the supernova is far brighter than its home galaxy, appearing as an extra star. ...

... Dark energy is believed to be a component of the Universe whose repulsive gravity is presently accelerating the expansion of the Universe.�� Although it comprises the bulk of the mass-energy of the Universe, its nature is not well understood.�� ��Albert Einstein originally suggested its existence about 80 years ago. A supernova is the explosive death of a star, which unleashes a burst of light through the cosmos. ... This website is a gift from Nancy Riess . ...

We have undertaken a survey for H I 21-cm absorption within the host galaxies of z 1.2-1.5 radio sources, in the search of the cool neutral gas currently `missing' at z > 1. ... From this, we obtain one detection out of 10 sources searched, which at z = 1.278 is the third highest redshift detection of associated 21-cm absorption to date. ...

Second Image Taken on March 12 at 8:52 UT. ... The supernova is the same brightness as in the previous image taken 2 hours ago . ... This image, taken 24 hours after the previous image, shows the supernova to be another 0.21mag (or about 25%) brighter. ... Hopefully the images do show that the brightness of the Supernova is changing. ...

Supernovae come in various forms, with different causes, but in general terms they��represent either��the explosive death of a giant star, or a very violent episode in the life of a binary star pair. Visually, they are the greatest explosions we see in the universe, with the exploding star sometimes becoming as bright as the combined light of all the other hundreds of millions of stars in its parent galaxy! ...

... STScI-PRC01-04 HUBBLE'S ULTRAVIOLET VIEWS OF NEARBY GALAXIES YIELD CLUES TO EARLY UNIVERSE Astronomers are using these three NASA Hubble Space Telescope images to help tackle the question of why distant galaxies have such odd shapes, appearing markedly different from the typical elliptical and spiral galaxies seen in the nearby universe. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
