... Keplers Supernova Remnant in X Rays . ... Some type of star exploded to create the unusually shaped nebula known as Kepler's supernova remnant , but which type? ... Recent X-ray data and images of Kepler's supernova remnant taken by the orbiting Chandra X-ray Observatory has shown relative elemental abundances more typical of a Type Ia supernova , indicating that the progenitor was a white dwarf star that exploded when it accreted too much material and went over Chandrasekhar's limit . ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...

... In the picture it looks like a peaceful place, but astronomers have spotted the violent explosions of two stars in this galaxy over the past 30 years. The explosion of a massive star is called a supernova. ... The first supernova that was spotted in this galaxy was discovered by professional astronomers, using a big telescope that is based in the desert in the country Chile in South America. ... Any changes in the brightness of an area of the galaxy could mean that a star has exploded. ...

10. (S-7a) The Black Hole at the Center of our Galaxy
... 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. ...

. The Tycho supernova remnant is the result of a type Ia supernova explosion. The explosion was observed by Danish astronomer Tycho Brahe in 1572. More than 400 years later, the ejecta from that explosion has expanded to fill a bubble 55 light-years across. In this image, low-energy X-rays (red) show expanding debris from the supernova explosion and high energy X-rays (blue) show the blast wave тАФ a shell of extremely energetic electrons.

... A full set of flatfield frames was taken with the NICMOS arrays during the System Level Thermal Vacuum test, conducted on the ground in August 1996. ... Users are encouraged to recalibrate their data with on-orbit flatfields if the pipeline calibration used thermal vacuum flatfields. Preliminary results from SMOV indicate that variations in the large scale structure of the on-orbit flatfields relative to the thermal vacuum flatfields are of the order of 1-2% in Camera 2, and up to 5% in Camera 1. ...

15. ASP: An Ancient Universe - Supernova 1987a
An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . SUPERNOVA 1987a . This Hubble Space Telescope image shows the remnant of a supernova a star that blew itself to pieces. We first saw the light of the explosion on Earth in 1987, and this image was taken in 1994. The remnant of the explosion itself is the blob of stuff in the center; the rings are regions of material ejected by the star earlier in its death throes. ... Return to An Ancient Universe . ...

16. Evolutionary Scenarios of Binary Systems
... To avoid extensive numerical calculations in the statistical simulations, we treat the continuous evolution of each binary component as a sequence of a finite number of basic evolutionary states (for example, main sequence, red (super)giant, helium (Wolf-Rayet) star, hot WD), in which stellar parameters significantly differ from each other. ...

18. Polar Orbiting Satellites
Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. A low altitude polar orbit is widely used for monitoring the Earth because each day, as the Earth rotates below it, the entire surface is covered. ... A different choice was made for MAGSAT, orbited 1979-80 to survey the Earth's own magnetic field near its surface. ...
