Star Shock Wave


If you thought shock waves  were only for science fiction movies, look again. JPL in Pasadena captured this infrared image of a shock wave created by a speeding star named Kappa Cassiopeiae. I have seen various movies and science fiction shows in which a star explodes and creates a shock wave that can destroy ships and space stations but to see an actual shock wave is pretty cool besides being quite beautiful.  NASA’s Spitzer Space Telescope is responsible for the image.

The Milky Way




I have visited a website called StarDate.org for many years now because I like the information they provide  in a brief and informative way. At a glance I can know what to expect in the night sky and plan if I am going to stay up late or get up early! This week from StarDate:



September 18

The glowing band of the Milky Way arches high across the sky this evening. Almost directly overhead, in the cross-shaped constellation Cygnus, it splits into two bright ribbons of stars. They rejoin in the southern constellation Centaurus.
When I read about the glowing band of the Milky Way, I remember a night hike I took many years ago with a Forest Ranger, some good friends, and others interested in the night sky. I went on that hike almost 30 years ago but I remember it like it was yesterday, it was one of those moments frozen in time in my mind. I was in Sequoia National Park in the southern portion of the Sierra Nevada at about 4000m high, so you can imagine the sky, it was amazing and filled with stars, satellites, and of course, the Milky Way band. It was an incredible sight to see, the images are ingrained in my mind. I wish the night sky were that clear in every part of the world and I could step out on my roof and once again see the Milky Way!

Updated Hubble Telescope









I love the Hubble Telescope because it provides such interesting information and images that make me want to dream about what kind of life lives out at the edges of the Universe. I thought it very clever that the movie "Contact" based on the book by the same name and written by Carl Sagan, used a variety of images produced by the Hubble Telescope in the opening sequences of the movie.
Hubble is still hard at work providing insight into the far reaches of the Universe.

Astronaut repairmen had hardly finished tightening the last stubborn bolts on the Hubble Space Telescope last summer when astronomers set the controls on the refurbished telescope to the dim and distant past.The result was a new long-distance observing record. Astronomers announced in a series of papers over the fall and in a news conference last week that Hubble had recorded images of the earliest and most distant galaxies ever seen, blurry specks of light that burned brightly only 600 million to 800 million years after the Big Bang.The specks are clouds only one-twentieth the size of the Milky Way galaxy and only 1 percent of its mass, and seem to show the lingering effects of the first generation of stars to form in the universe in that they get bluer the farther back you go in time.
