To date, the Kepler space telescope has found more than 1,200 likely planets orbiting stars beyond the sun quite a haul for a satellite that’s been flying for just over two years. The true prize Kepler is hunting for, of course, is not just any planet, but one that’s a twin of Earth about the size of our world, orbiting in a zone where the temperature range is like ours
What is creativity?
The star known as Gliese 581 is utterly unremarkable in just about every way you can imagine.
The orbiting Kepler telescope is all about the numbers. How many stars have planets
Scientists at NASA have discovered a nearly invisible ring around Saturn — one so large that it would take 1 billion Earths to fill it.
In an unusual step, NASA scientists interrupted testing of the refurbished Hubble Space Telescope to aim the orbiter’s camera at Jupiter and capture an image of the planet’s mysterious new scar. The resulting picture, taken Thursday, is the sharpest visible-light photo of the dark spot and Hubble’s first science observation since astronauts repaired and upgraded it in May, NASA said. Earth-based telescopes have been trained on Jupiter since an amateur astronomer in Australia noticed the new mark, probably created when a small comet or asteroid plunged into Jupiter’s atmosphere and disintegrated, early Monday
The space shuttle Atlantis crew began its final spacewalk to upgrade the Hubble Space Telescope on Monday morning. If all goes as planned, it will be the last time human hands touch the orbiting telescope, which has provided astronomers distant images that have helped them see further into the origins of the universe.
