Here at Science World, one of our favorite topics is the sun. We’ve been able to provide you with a number of informational pieces regarding events and phenomena such as the ebb and flow of the sun’s activity throughout its roughly 11 year solar cycle. As the sun goes through this process – from when […]
Over the past several years, NASA spacecraft studying the sun have sent back some spectacular images of it exploding with solar flares and coronal mass ejections. Now, scientists say that two of these spacecraft — the Solar Dynamics Observatory (SDO) and the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) — have detected a phenomenon […]
Did you know that the Sun’s outer atmosphere, or corona, is much hotter than its surface? Scientists have been quite curious about a mysterious interface region of the Sun’s atmosphere that amplifies energy from about 5,800 degrees Kelvin on the surface, or photosphere, to around 1,000,000 degrees Kelvin in the corona. With Thursday’s launch of […]
NASA‘s newest rover could help scientists better understand changes in the massive Greenland ice sheet. Last summer, higher-than-normal temperatures caused surface melting across about 97 percent of the ice sheet. Scientists expect the robot to detect the layer of the sheet, which is buried beneath two miles of ice, that formed after last year’s extreme […]
NASA wants to shorten the journey to Mars. It took about eight months for its Mars rover, Curiosity, to reach the red planet. And now, the US space agency is looking for ways to cut the travel time for future manned missions there. Researchers in Washington State say that might be possible through a unique […]
NASA scientists have discovered a third radiation belt briefly surrounded Earth for about a month before being blasted away by an interplanetary shock wave from the sun. Experts had long thought there were only two distinct regions of trapped radiation. But the third ring was spotted by twin Van Allen radiation probes NASA launched in 2012 […]
While in space and orbiting the sun this celestial body is an asteroid. It’s a meteor as its entering earth’s atmosphere, like a fireball flashing across the sky and a meteorite is the actual object that made it to Earth.
