asymmetric galaxy

Asymmetric galaxy discovered
The Hubble telescope and the MPG / ESO 2.2-meter star images have captured opposing Meathook asymmetric spiral galaxy, or NGC 244. Astronomers report that NGC 244 has an extraordinarily asymmetric spiral arm is folded upon itself and contains a recent supernova, while the other, punctuated by newly formed stars, extends from the nucleus.

The densest solid exoplanet
The planet, called 55 Cancri e, 40 light years from Earth, is 60 percent larger in diameter than Earth, but eight times more massive. The densest planet known so far is only twice as much as ours. 55 Cancri and circling the star 55 Cancri A, so close that its year is less than 18 hours. "You could measure the dates Cancri a wristwatch instead of a timetable," says astronomer Jaymie Matthews.
