Astronomers find a planet denser than lead

From the Bad Astronomer (who is better at quoting sources than I am):

Meet the planet COROT-exo-3b. It orbits a star slightly larger, hotter, and brighter than the Sun. The star is not an unusual one in any way, but the planet is definitely weird: it orbits the star in just over 4 days, which is pretty close in, though not a record breaker in and of itself. What’s bizarre is that it has about the same diameter of Jupiter, but has 21.6 times Jupiter’s mass. That makes it denser than lead.

Deep Sea Critters

'Deepest ever' living fish filmed

The "deepest ever" living fish have been discovered, scientists believe.

A UK-Japan team found the 17-strong shoal at depths of 7.7km (4.8 miles) in the Japan Trench in the Pacific - and captured the deep sea animals on film.

The scientists have been using remote-operated landers designed to withstand immense pressures to comb the world's deepest depths for marine life.

Monty Priede from the University of Aberdeen said the 30cm-long (12in), deep-sea fish were surprisingly "cute".

The fish, known as Pseudoliparis amblystomopsis, can be seen darting about in the darkness of the depths, scooping up shrimps."

There's a short video at the BBC showing the fish in action, as well as more of the report.
