Armagh Observatory reports that, if skies are clear on the night of 27/28 September, skywatchers will witness a rare total eclipse of the Moon during the early hours of Monday 28th. ... As the eclipse progresses from penumbral to partial phase, and then towards totality, it is interesting to observe how the dark shadow of the Earth slowly encroaches on the Full Moon until the Moon is nearly completely obscured. ...

... September 5, 1998 . The Pulsar Powered Crab . Credit: J. Hester and P. Scowen ( ASU ), NASA . ... Using a stunning series of visible light images taken with the Hubble Space Telescope (HST) , astronomers have discovered spectacular pulsar powered motions within the Crab nebula. Highlights of this HST Crab "movie" show wisps of material moving away from the pulsar at half the speed of light, a scintillating halo, and an intense knot of emission dancing, sprite-like, above the pulsar's pole. ...

... Take a few moments to take in all of the wonderful details captured in this new photo of some baby stars in a glowing cloud of gas. ... Here, the gas cloud hasn t been photographed because there are dark clouds called Bok Globules blocking the view. ... This invisibility cloak, though, has a weakness: It fails when astronomers look at the Bok Globules using a special type of telescope that detects infrared light. ... And infrared light can also travel through the dust inside Bok Globules. ...

... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...
