SIMBAD Astronomical Database SIMBAD on the Web is the WWW interface to the SIMBAD database. It offers the following functionalities: Query by identifiers and around identifiers Query by coordinates, specifying the radius and the equinox Query by bibcode and partial bibcode Sampling with a set of physical criteria Query by lists of objects, coordinates or bibcodes Display charts for list of objects resulting from coordinates query Moreover, the interface provides links with many other data services :
Top 40 Useful Sites To Learn New Skills The web is a powerful resource that can easily help you learn new skills. You just have to know where to look. Sure, you can use Google, Yahoo, or Bing to search for sites where you can learn new skills , but I figured I’d save you some time. Here are the top 40 sites I have personally used over the last few years when I want to learn something new. Felix Baumgartner Skydives From The Edge Of Space [11 High Quality Photos] Red Bull is supposed to give you wings bit that would only slow Felix Baumgartner down. This week the daredevil made a test skydive from 18 miles up in preparation for his upcoming jump from 120,000 feet (22 miles) in which he hopes to reach speeds of 690 MPH and be the first person the break the sound barrier. In the latest test jump Felix went 0 to 509 MPH in just 30 seconds and all that is without the aid of a plane fo rocket, just pure gravity baby! Here are photos from his latest jump… Felix Baumgartner hugs Capcom 1 USAF Col (ret) Joe Kittinger after his 96,640 ft free fall from the stratosphere making them the only two people to freefall from that high an altitude.
Sirius Sirius appears bright because of both its intrinsic luminosity and its proximity to Earth. At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite, the Sirius system is one of Earth's near neighbors. Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years. After that time its distance will begin to recede, but it will continue to be the brightest star in the Earth's sky for the next 210,000 years. 10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely.
Groundbreaking Tower in Singapore is Draped in Greenery WOHA Architects are completely changing how skyscrapers are built with their Park Royal Tower in Singapore, which will feature twice as much greenery as the nearby Hong Lim Park. The high-end office and hotel tower features a podium absolutely overrun with vertical gardens, contoured green pathways, water features, and leafy terraces. When it is completed later this year, this groundbreaking project will boast a whopping 15,000 square meters of green space! Humans Left Africa Earlier, During Ice Age Heat Wave A warm spell during the Ice Age gave early humans a route out of Africa 20,000 years earlier than thought, say scientists who've uncovered a prehistoric tool kit in Arabia. During this period of climate change , about 130,000 years ago, water travel would have been easier than in more typical Ice Age periods. Seas in the region would still have been at relatively low, Ice Age levels, making for shorter crossings. On top of that, though, warmer, wetter weather would have created navigable lakes and rivers in what are now the deserts of the Arabian Peninsula, the study says. Such a shift would have offered early modern humans—which arose in Africa about 200,000 years ago—a new route through the formerly parched northern deserts into the Middle East.
Will Its Violent Death Impact Earth? The red giant, once so large it would reach out to Jupiter's orbit if placed in our own solar system, has shrunk by 15 percent over the past decade in a half, although it's just as bright as it's ever been. "To see this change is very striking," said retired Berkeley physics professor Charles Townes, who won the 1964 Nobel Prize for inventing the laser. "We will be watching it carefully over the next few years to see if it will keep contracting or will go back up in size." Betelgeuse, whose name derives from Arabic, is easily visible in the constellation Orion.
Stars & Planets Scale Comparison A Humbling Perspective"Things are not what they seem, nor are they otherwise." This scale comparison shows "the true place" of Earth and our Sun among the various giants of the universe. It is simultaneously sobering and mind-boggling experience.First series of images opens with the Death Star compared to Mimas, one of Saturn's moons. Note the similarities between the two :)
