There was an evolutionary theory that suggested gas giants similar to that of Jupiter in our solar system, take an enormous amount of time to be created. Estimated time, supposedly hundreds of millions of years. New observational data has changed that even for some evolutionists…
“Even though astronomers have detected hundreds of Jupiter-mass planets around other stars, our results suggest that such planets must form extremely fast.”
“Whatever process is responsible for forming Jupiters has to be incredibly efficient,” said lead researcher Thayne Currie of the Harvard-Smithsonian Center for Astrophysics. Currie presented the team’s findings at a meeting of the American Astronomical Society in Long Beach, Calif.” –Center for Astrophsyics
The center of the Milky way revealed some interesting observational data…Young stars were found circling a massive black hole. This discovery has puzzled scientists. Because the tides from the black hole should rip those molecular clouds that act as stellar nurseries. As a result, it prevents the stars from forming in place.
Speaking of the Milky way, the size was underestimated by astronomers. New observational data suggests that the Milky way is much larger, bulkier, and spinning faster than previously thought.
More good news in astronomy, NASA’s Hubble Space Telescope spots 14 young stars by accident which are traveling at incredibly high speeds. Classified as new class of high-velocity stellar interlopers.
The objects observed by Hubble are not very massive because they do not have glowing clouds of ionized gas around them. They are medium-sized stars that are a few to eight times more massive than the sun. The stars are not old because the shapes of the nebulae around aging, dying stars are very different, and old stars are almost never found near dense interstellar clouds.
“Depending on their distance from Earth, the bullet-nosed bow shocks could be 100 billion to a trillion miles wide (the equivalent of 17 to 170 solar system diameters, measured out to Neptune’s orbit).
The bow shocks indicate that the stars are traveling fast, more than 180,000 kilometers an hour (more than 112,000 miles an hour) with respect to the dense gas they are plowing through, which is roughly five times faster than typical young stars.” –NASA
More discoveries were made with the Chandra X-ray Space Telescope. 2009 is being promoted as the year for astronomy. Marking the 400th anniversary of the first use of an astronomical telescope by Galileo.
“The heavens declare his righteousness, and all the people see his glory.”
Without the evolution spin to it, astronomy has always been a fascinating science. Due to human limitations, we can only explore from a great distance but wow, what a sight!
