... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

My research efforts have focused on three areas which are: . More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to the reflex motions of their host stars, and more recently through transits of some planets across the face of the host stars. ... Gravitational microlensing provides a novel technique to look for planets around lens stars, and this is the only technique currently capable of detecting Earth-mass planets. ...

... The TRACE images may be used without restrictions in publications of any kind. ... These two images, taken on 18 November 2000 at 15:54UT and 16:11UT, respectively, show such an event: the red circle in the image to the left shows a region where many loops are cooling, with bright loop tops (the intensity scales with the square root of the image to reduce the dynamic range). ...

... Venus, the brightest planet, and Jupiter the second brightest (apart from Mars on very rare occasions) will appear very close together in the Eastern morning sky! ... Venus will be magniute -4.0, and Jupiter mag. ... Callisto, Jupiter's outermost Galilean moon, will then be 7' to the West of Jupiter, so Venus will be just about 4.5 times further away. ... The Last Quarter Moon will be 55 degrees away to the upper right of Venus, with Saturn (mag 0.1) another 16 degrees beyond the Moon. ...

... Makemake, a dwarf planet in our Solar System, appears to have no atmosphere; it is bald! ... Until a few years ago, Pluto was considered to be the most distant planet, until it was downgraded to a dwarf planet like Makemake. ... If there was an atmosphere around Makemake, the star would have slowly faded away as the dwarf planet blocked it. ... Cool fact: Beside Makemake there are four other known dwarf planets in our Solar System: Pluto, Ceres, Haumea and Eris. ...

. Uranus' edge-on rings appear as spikes above and below the planet. The rings cannot be seen running fully across the face of the planet because the bright glare of the planet has been blocked out in the photo (a small amount of residual glare appears as a fan-shaped image artifact, along with an edge between the exposure for the inner and outer rings).
