A massive alien planet that may have been ripped into Earth-size chunks by its dying parent star is offering a unique glimpse into the evolution of other worlds and their stars, scientists say. Continue reading
On May 5, 6 we witnessed the Eta Aquarids Meteor Shower. It is a a light shower, usually producing about 10 meteors per hour at the peak. The full moon ruined the show this year, washing out all but the brightest meteors with its glare. Continue reading
A group of European astronomers has discovered an ancient planetary system that is likely to be a survivor from one of the earliest cosmic eras, 13 billion years ago. The system consists of the star HIP 11952 and two planets, which have orbital periods of 290 and 7 days, respectively. Continue reading
On April 15 the planet Saturn will be at Opposition. The ringed giant will be at its closest approach to the Earth and its face will be fully illuminated by the Sun. It will be the best time to view … Continue reading
With President Barack Obama proposing a relatively flat budget for NASA in 2013, a group professional astronomers is urging the White House and Congress to find a better balance between the space agency’s planetary science and exploration needs. Continue reading
On March 3, Mars was at opposition. The Earth passed Mars as the two planets wheeled around the sun in their respective orbits. This time the opposition was an unfavorable one because Mars was at aphelion on February 15, which … Continue reading
NASA’s Galaxy Evolution Explorer, or Galex, was placed in standby mode Feb. 7, 2012 as engineers prepare to end mission operations, nearly nine years after the telescope’s launch. The spacecraft is scheduled to be decommissioned — taken out of service — later this year. Continue reading
The best chance to see Mercury will be from February 20 to March 12. The planet will, from our point of view, have moved far enough from the Sun’s glare to be visible shortly after sunset. Mercury will reach greatest elongation from the Sun on March 5, reaching a relatively bright magnitude of about -1. Continue reading
Scientists help define structure of exoplanets. Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. Continue reading
Astronomers using the partially completed ALMA observatory have found compelling evidence for how star-forming galaxies evolve into ‘red and dead’ elliptical galaxies, catching a large group of galaxies right in the middle of this change. Continue reading
