Ultra-high energy cosmic rays come from outside our galaxy

New York: Researchers have found that some ultra-high energy cosmic rays that occasionally hit Earth come from a distant source outside the Milky Way. Cosmic rays are atomic nuclei that travel through space at speeds close to that of light. Low-energy cosmic rays come from the Sun or from our own galaxy, but the origin […]

NASA'S OSIRIS-REX mission to flyby Earth on Friday

Washington: NASA’s asteriod hunting OSIRIS-REx spacecraft is all set to make a close flyby of Earth on Friday, before reaching asteroid Bennu, media has reported. The Earth’s gravity will fling the OSIRIS-REx spacecraft, travelling at a staggering speed of 19,000 miles (30,758 km) per hour, upward by about six degrees so that its trajectory will […]

How Milky Way differs from other galaxies

New York: Our galaxy, which is home to Earth and its solar system, might not be as “typical” as previously thought, and therefore Milky Way-based models to understand other galaxies of the universe could be misleading, new research suggests. “We use the Milky Way and its surroundings to study absolutely everything,” said Marla Geha of Yale […]

How do hurricanes form? Know from NASA scientists

Washington: Even as Hurricane Harvey left Texas bruised and Hurricane Irma began lashing Florida, NASA scientists have explained in a blog how hurricanes form and what steps the US space agency has taken to study the most violent storms on Earth. People call these storms by other names, such as typhoons or cyclones, depending on […]

NASA probes detect man-made bubble around Earth

Washington: Humans have long been shaping Earth’s landscape, but now scientists know that we also can shape our near-space environment with radio communications. The impact of such communications extend out beyond our atmosphere, creating a bubble surrounding Earth, NASA’s Van Allen Probes, which study electrons and ions in the near-Earth environment, have revealed. A certain […]

Life on land originated 580 million years earlier than thought

Melbourne: Deposits preserved in 3.48 billion-year-old rocks formed in ancient hot springs in Western Australia provide evidence that microbial life on land originated 580 million years earlier than thought, according to a study. Besides shedding new light on the origin of life on Earth, the researchers believe that their findings have major implications for the […]

NASA releases new global maps of Earth at night

Washington: NASA has released its latest global maps of Earth at night, providing the “clearest yet composite” view of the patterns of human settlement across our planet. Satellite images of Earth at night — often referred to as “night lights” — have been a tool for fundamental research for nearly 25 years. They have provided […]

At least nine alien planets in position to spot Earth

UK/Germany: In a bid to find how alien observers might be able to detect Earth, scientists have found that at least nine exoplanets are ideally placed to observe the transits of our world. Scientists from Queen”s University Belfast in the UK and the Max Planck Institute for Solar System Research in Germany turned exoplanet-hunting on […]

Pluto plain resembles frozen mud cracks on Earth

Washington: A close-up image of Pluto has revealed a vast, craterless plain – resembling frozen mud cracks on Earth that appears to be no more than 100 million years old and is still being shaped by geologic processes. This frozen region is north of Pluto’s icy mountains, in the centre-left of the heart feature named […]

Number of distant galaxies fewer than thought

New York: The number of distant galaxies could be 10 to 100 times fewer than earlier thought, astronomers estimate. Over the years, the Hubble Space Telescope has allowed astronomers to look deep into the universe. The long view stirred theories of untold thousands of distant, faint galaxies. “Our work suggests that there are far fewer […]
