how did that H20 get to our planet? The hydrogen came from the solar nebula, but where did the oxygen come from?
The astronauts on board the International Space Station saw a strange and unexpected view out their windows yesterday. “Saw something launch into space today. Not sure what it was but the cloud it left behind was pretty amazing,” tweeted NASA astronaut Mike Hopkins.
One of the original “Mercury 7” astronauts, Scott Carpenter, has died. He was the sixth person to fly in space; the fourth American to fly in space and the second US astronaut to orbit Earth. Carpenter died on Thursday, October 10, 2013 at age 88 after suffering a recent stroke. With the death of Carpenter, the only remaining surviving member of the original US astronauts is John Glenn.
The planetary world keeps getting stranger. Scientists have found free-floating planets — drifting alone, away from stars — before. But the “newborn” PSO J318.5-22 (only 12 million years old) shows properties similar to other young planets around young stars, even though there is no star nearby the planet.
Ask anyone, “what color is the Sun”? and they’ll tell you the obvious answer: it’s yellow.
But is it really?

But in this case, it is… a lost moon of Neptune not seen since its discovery in the late 1980′s.
A new announcement from the 45th Meeting of the Division for Planetary Sciences of the American Astronomical Society being held this week in Denver, Colorado revealed the recovery of a moon of Neptune that was only briefly glimpsed during the 1989 flyby of Voyager 2.
For millennia, human eyes have seen only one face of the moon. Put a dude from the Iron Age in a time machine and whisk him to 2013 and he’d see the same pattern of light lunar highlands punctuated by dark grey spots you see. Night after night after night.
That all changed 54 years ago today when the Soviet Union’s Luna 3 probe opened its camera shutter and snapped the first pictures of the lunar far side.
That was fast! Just one year after a Higgs Boson-like particle was found at the Large Hadron Collider, the two physicists who first proposed its existence have received the Nobel Prize in Physics for their work. François Englert (of the former Free University of Brussels in Belgium) and Peter W. Higgs (at the University of Edinburgh in the United Kingdom) received the prize officially yesterday.
View of a shooting star (Draconid) and northern light near Skekarsbo, Sweden (AFP Photo Scanpix P-M Heden) The unpredictable Draconid meteors are to dart through the dome of the night sky allowing stargazers to observe a fiery display of shooting stars on Monday and Tuesday peaking right after nightfall. While most similar celestial shows […]
In this video, Professor Brian Cox considers the death of the Universe, a time so far in the future it defies comprehension. Brian discovers that time is not characterised by repetition but by irreversible change. From the relentless march of desert sands to the erosion of a beached freighter, the ravaging effects of time are […]
The Universe is constantly expanding. While we may take this knowledge for granted now, it was only ratified in the late 90s. Before that it was equally possible that the Universe was in fact contracting. In this video our Head Squeeze presenters Tom and Andrew explain the concept of ‘dark energy’ and why it’s making […]
A new study, however, cautions that the X-ray environment of these dwarfs may give us false positives. They looked at Earth-mass planets in the neighborhood of four stars, such as GJ 667 (which has three planets that could be habitable), and concluded it’s possible for oxygen to reside in these planets even in the absence of life.
NASA’s MAVEN Mars orbiter granted ‘Emergency Exemption’ to Resume Processing during Government Shutdown
Following a three day period of complete work stoppage due to the US Government Shutdown, technicians late today (Oct. 3) resumed critical launch preparations for NASA’s next mission to Mars, the MAVEN orbiter. And it’s not a moment too soon, because the consequences of a continued suspension would have been absolutely dire for the entire future of Mars exploration!
Fomalhaut is a really cool place to study. The naked-eye star (the brightest star in the constellation Piscis Austrinus) has a planet, Fomalhaut b, that once appeared dead but rose again in science circles. It is the site of a comet massacre. Now it’s getting even more interesting: Scientists have believed for years that Fomalhaut is a double star, but a new paper proposes that it is actually a triplet.
