Etretat, Sunset, February 5th, 1883, 4:53 PM local time

Dating an Impressionist's Sunset. "Famed French Impressionist Claude Monet created a striking scene of the Normandy coast in his 1883 painting, Étretat: Sunset. Now a team of Texas State University researchers, led by astronomer and physics professor Donald Olson, has applied its distinctive brand of forensic astronomy to Monet’s masterpiece, uncovering previously unknown details about the painting’s origins."

Planck unveils the Universe

Planck telescope reveals ancient cosmic light. "The picture is the first full-sky image from Europe's Planck telescope which was sent into space last year to survey the oldest light in the cosmos. It took the 600m-euro observatory just over six months to assemble the map. It shows what is visible beyond the Earth to instruments that are sensitive to light at very long wavelengths - much longer than what we can sense with our eyes." [more inside]

Bubble Nebula

Reprocess of Bubble Nebula Data. NGC 7635, also called the Bubble Nebula, is an emission nebula in the constellation Cassiopeia. It's created by stellar winds from a superhot star 40 times the size of our sun which whip the cloud of gas around the star into a bubble. [Via]

Gamma-Ray Burst

New burst vaporizes cosmic distance record. "NASA's Swift satellite and an international team of astronomers have found a gamma-ray burst from a star that died when the universe was only 630 million years old, or less than five percent of its present age. The event, dubbed GRB 090423, is the most distant cosmic explosion ever seen."

Venus's Missing Water

Where did Venus’s water go? Water may have once been as abundant on Venus as it is on Earth. New data from the Venus Express suggests that the planet's lack of a magnetic field has allowed water in the atmosphere to be stripped apart and carried into space by the solar wind.

Solstice at Newgrange

At dawn on the winter solstice, the passage and chamber of the megalithic passage tomb at Newgrange are illuminated for 17 minutes by a shaft of sunlight entering through the roofbox above the entrance. The builders of Newgrange achieved this precise alignment over 5,000 years ago, 1,000 years before Stonehenge. You can watch the sunrise illumination on a live webcast between 08:30 and 09:30 UTC on Sunday, December 21st.

Dark Flow

Mysterious New 'Dark Flow' Discovered in Space. "As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon 'dark flow.' The stuff that's pulling this matter must be outside the observable universe, researchers conclude." [more inside]

Archaeoastronomy in Peru

The Thirteen Towers of Chankillo in Peru may be the Western Hemisphere's oldest known full-service solar observatory, showing evidence of early, sophisticated Sun cults, according to archaeoastronomy professor Clive Ruggles. The 2,300-year-old complex featured 13 towers running north to south along a ridge and spread across 980 feet to form a toothed horizon that spans the solar arc. Last year, another ancient observatory was discovered in Peru by Robert Benfer. The Temple of the Fox is 4,200 years old, making it 1,900 years older than the Chankillo site, but wasn't a complete calendar.

Spitzer Space Telescope

The first images from the Spitzer Space Telescope, formerly known as the Space Infrared Telescope Facility and renamed after astrophysicist Lyman Spitzer, Jr., were released on Thursday. Launched on August 25, it obtains images by detecting the infrared energy radiated by objects in space, and it will drift behind the Earth as the planet orbits the sun.
