| White Dwarfs in a Death Spiral | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| May 31, 2005 - New observations from the Chandra X-Ray Observatory have discovered two white dwarf stars orbiting one another at a tremendous speed - they're only 80.000 km (50,000 miles) apart! The rate at which they're orbiting is decreasing by 1.2 milliseconds every year, which means they're destined to eventually collide. What's important about this find is that the stars are probably creating gravity waves, as predicted by Einstein, and these gravity waves should increase as they get closer and closer. (Full Story) |

| Twin Black Holes Churn at the Heart of M83 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| May 18, 2005 - Most galaxies, like cells in the body, have only a single nucleus in their midst - but a few have more. Now a team of astronomical sleuths from Argentina have used some advanced observational and software analysis methods to determine that 15MLY distant M83 is one of the few. Could the unique gravitational effects of having two such mass concentrations (SMBHs?) account for the numerous massive super-cluster star-formation regions associated with this 30-thousand light year diameter grand spiral galaxy?

| The Birth of a New Black Hole? | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| May 11, 2005 - Monday's gamma ray burst might have been just what astronomers have been hoping to see for decades - the birth of a new black hole. GRB 050509B was a short gamma ray burst, lasting only 50 milliseconds, which means it could be the result of a collision between two neutron stars, or even two black holes. NASA's Swift observatory detected the explosion, tracked its location, and focused its large telescope within a minute of its occurrence. (Full Story) |

| Solar Minimum Doesn't Mean a Calm Sun | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| May 6, 2005 - Our star goes through an 11-year cycle of solar activity. At the recent height of the cycle, the Sun blasted off some of the most powerful flares and coronal mass ejections ever seen. And during the minimum, due in 2006, it's supposed to be calm, right? Well, not exactly. Even during the lowest point of solar activity, the Sun still blasts off a few of the most powerful X-class flares. Unprotected astronauts caught in the radiation would probably get pretty sick.

| Near Perfect "Einstein Ring" Discovered | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Apr 29, 2005 - Gravitational lensing happens when the gravity of a relatively close galaxy acts as a telescope lens to focus the light from a more distant galaxy. It allows astronomers to see distant objects they could never have a hope of observing with current instruments, essentially looking back to moments after the Big Bang (cosmically speaking). The galaxies are never perfectly lined up, though, and the "natural telescope" is a bit blurry. (Full Story) |

| Ripples in Spacetime Could Explain Dark Energy | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Mar 18, 2005 - An international team of astrophysicists have developed a new theory to explain the accelerating expansion of the Universe, known as "dark energy". Instead of a mysterious energy which is pushing matter apart at an accelerating rate, the team believes it could be the natural outcome of ripples in space and time created during the earliest moments of inflation after the Big Bang. These ripples could extend beyond what we can see with our telescopes, so we can only calculate their existence. (Full Story) |

| Black Holes Might Obscure Earliest Times | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Mar 10, 2005 - Astrophysicists from Penn State University are concerned that the light bending effects of gravity around black holes might be so severe that early times in the Universe might be impossible to study. Gravitational lenses, where the gravity of one galaxy serves to focus the light from a more distant galaxy, have been used to study deeper into space than would normally be possible. But in the close vicinity of black holes, light is bent in unpredictable ways, completely obscuring the direction of the source. (Full Story) |

| Feb 17, 2005 - In some ways, the bright auroras at Saturn's poles are very similar to our own Northern/Southern lights here on Earth. But in other ways, they're very different, and it's a mystery that has been puzzling astronomers since they were first discovered 25 years ago. Saturn's auroras can brighten for days (compared to minutes here Earth), and can stay still while the planet rotates underneath. (Full Story) |

Touchdown! Huygens Lands on Titan Huygens Probe Returns First Images of Titan's Surface | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Jan 14, 2005 - After a seven year journey, the European Space Agency's Huygens probe is now on the surface of Titan. The probe entered Titan's smoggy atmosphere right on time, and slowed itself down using a series of parachutes. It then gathered data using its camera and science instruments for just over 2 hours until it landed. The probe then relayed all its data through Cassini back to Earth, where scientists will be poring over it for years. Preliminary data indicate that the probe did land safely on some kind of solid surface. (Full Story) |

| Iapetus Has a Seam | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Jan 10, 2005 - Scientists already considered Saturn's moon Iapetus unusual, because of its strange two-toned appearance; one hemisphere is dark, while the other is bright. But new images from Cassini show an even more unusual mystery: it has a seam. It's 20 km (12 miles) high and runs 1,300 km (808 miles) directly around Iapetus' equator. In some places, this ridge is so high it rivals Olympus Mons, which is unusual for an object which is 1/5th the mass of Mars. Researcher will have to wait until September 2007 for Cassini's next pass. (Full Story) |

| Biggest Eruption in the Universe | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Jan 6, 2005 - Astronomers have used the Chandra X-Ray Observatory to watch the most powerful eruption ever seen in the Universe. The eruption is coming from the heart of a distant galaxy cluster called MS 0735.6+7421; it's been going on for more than 100 million years, and generated the equivalent energy of hundreds of millions of gamma-ray bursts. Astronomers believe that this energy is being released because a supermassive black hole has sucked in more matter than it can consume - the mass of 300 million Suns is being swallowed.

| Jan 3, 2005 - The powerful Gemini Observatory took this image of spiral galaxy NGC 6946, which is awash in star formation. This image was taken with a special filter designed to highlight the regions of star formation. Astronomers aren't sure why this galaxy is so furiously building new stars, compared to the other galaxies in our local neighborhood. And all this starbirth leads to supernovae, which are explosions of massive stars that "live fast and die young." Just in the last century, astronomers have seen 8 supernovae explode - more than any other galaxy ever observed. (Full Story) |

| Dec 22, 2004 - One of the highlights of Cassini's mission to Saturn is about to get underway, when the ESA's Huygens probe detaches from the spacecraft on December 24, and begins its solo journey to Titan. Once freed from Cassini, it'll remain in a dormant sleep until a timer wakes it up on January 14, shortly before it enters the moon's atmosphere. It will take 2.5 hours to pass through Titan's atmosphere, and it may even survive a landing on the moon's mysterious surface. (Full Story) |

| Planetary Systems Seen Forming | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Dec 10, 2004 - Both Hubble and the Spitzer Space Telescope have provided astronomers with a view of planetary systems forming around other stars similar to our own Sun. Hubble viewed a young star, only 50 to 250 million years old, which could have gas giants, but its rocky planets would still be forming. This could be a view into what our Solar System looked like when it was first forming. Spitzer found 6 much older stars with planetary disks; closer to 4 billion years old, which is the age of our Sun. (Full Story) |

| Nov 25, 2004 - Protoplanetary discs surrounding new stars seem to have the building blocks for rocky planets right from the start, according to new research from an international team of researchers. The astronomers used the European Southern Observatory's VLT Interferometer to examine the discs around three young stars, which were similar to what our own Sun looked like more than 4.5 billion years ago. They found that the inner part of these discs is very rich in sand, ready to be clumped by gravity into larger and larger rocks until full planets form. (Full Story) |

| New observations from NASA's Spitzer Space Telescope reveal surprisingly large dust clouds around several stars. These clouds most likely flared up when rocky, embryonic planets smashed together. The Earth's own Moon may have formed from such a catastrophe. Prior to these new results, astronomers thought planets were formed under less chaotic circumstances. (Full Story) |

| Astronomers using the Gemini observatories have got themselves a bit of a mystery. They've found a binary system at EF Eridanus, located 300 light-years away from Earth, where one of the objects defies classification. It's about the size of Jupiter but it's way too massive to be a planet. It's the temperature of a brown dwarf, but its light doesn't match a brown dwarf's characteristics. |

| This photo, taken by NASA's Cassini spacecraft, shows the tiny moon Prometheus, which serves as a shepherd to the inside edge of Saturn's knotted F ring. It's only 102 km (63 miles) long, so Cassini had to take several images of it, which were then stitched together on computer to enhance resolution and reduce noise. It was first discovered during the Voyager mission, and scientists saw a hint of the ridges, valleys and craters that marred its irregular surface. Cassini is expected to make a much closer flyby of the tiny moon later in its mission. (FULL STORY) |

| In March, NASA unveiled the Hubble Space Telescope's Ultra Deep Field (UDF), an 11.3-day exposure that represents humanity's deepest optical look into the universe. Althought it’s smattered with beautiful spiral and elliptical galaxies lying a few billion light-years from Earth, several teams of astronomers have focused on the faintest, farthest objects in the UDF — tiny red smudges that are barely discernible. While not exactly eye candy, these smudges were primarily responsible for one of the universe's most critical transitions: reionization. (FULL STORY) |

Since the Moon's cycle lasts 29 days, and most months are 30 or 31 days long, it can happen - usually every 30 months or so. Since there was a full Moon on July 2, the next one will happen on July 31. Of course, the Moon won't actually turn blue - it's just a saying. (FULL STORY) |

March 9, 2004 | This morning astronomers at the Space Telescope Science Institute (STScI) presented the deepest view yet of a small section of our universe. Dubbed the Hubble Ultra Deep Field (HUDF), the image of a 3-arcminute-square area in the constellation Fornax reveals 10,000 galaxies. Some 400 orbits were used between September 24, 2003, and January 16, 2004, to take more than 11 days worth of observations with the Advanced Camera for Surveys and another 4½ days with the Near-Infrared Camera and Multi-Object Spectrometer. Researchers will delve into the data to identify star systems that formed a few hundred million years after the Big Bang. Read the Full Story |
