It's a Star, Not a Planet.
It's a Star, Not a Planet
Atlantis Possibly Delayed by Rudder Problems
IT'S A STAR, NOT A PLANET
An unusual object in a long, thin nebula photographed by Hubble was
thought to be the first extrasolar planet directly imaged. Scrutiny has
revealed that the object is just too hot to be a planet: instead, it is likely
that the strange object is a background star, dimmed by interstellar dust.
The original observations identified the object as a potential young and
hot "protoplanet" several times larger than Jupiter.
ATLANTIS POSSIBLY DELAYED BY RUDDER PROBLEMS
A hydraulic problem in Atlantis' tail has jeopardized the launch set for later
this month. NASA is hoping to keep the shuttle on track: engineers are
spending a day or two collecting data to analyze the problem and come
up with a best solution. The Power Drive Unit for the shuttle's
rudder/speed brake shows hydraulic pressures three times normal, and
engineers are debating the feasibility replacing it on the launch pad, a
repair feat never performed in the history of the shuttle program.
European and North American skywatchers were treated to a spectacular
display of Northern Lights. The ACE spacecraft detected an incoming
cloud of magnetically charged particles, and scientist issued an auroral alert.
