... Spacecraft that will search for planetary systems around 40 million stars and observe the largest explosions in the universe have been chosen as the next two missions in NASA's medium-class Explorer (MIDEX) program. ... The first mission, to be launched in 2003, is the Swift Gamma Ray Burst Explorer, a three-telescope space observatory for studying gamma ray bursts. ... During its three-year mission, Swift will also survey the sky for new black holes and other sources of cosmic gamma rays. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

The SOHO spacecraft currently supplies daily images of the solar corona at 1.1-3, 2-6 and 4-30 solar radii. Are ground-based solar corona observations during total solar eclipses have becoming obsolete nowadays? A quick view of SOHO data shows that it is not perfect in some respects. ...

... 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. ...
