Oumuamua is the first known interstellar object detected passing through the solar system. When Astronomers first detected it in the year 2017, it was too late to study it properly. But within that brief period, it exhibited some unexpected properties which left astronomers scratching their heads. Its elongated shape, lack of coma and facts that … Read more
The long relationships between stars and the planets around them—including the Sun and the Earth—maybe even more complex than previously thought. This is one conclusion of a new study involving thousands of stars using NASA’s Chandra X-ray Observatory. By conducting the largest survey ever of star-forming regions in X-rays, a team of researchers has helped … Read more
NASA’s Juno spacecraft flew closer to Jupiter’s largest moon than any other in more than two decades, offering dramatic glimpses of the icy orb. The first two images from NASA Juno’s June 7, 2021, flyby of Jupiter’s giant moon Ganymede have been received on Earth. The photos – one from the Jupiter orbiter’s JunoCam imager … Read more
An analysis of new rock samples taken from NASA’s Curiosity rover uncovered evidence of clay minerals on Mars, suggesting the presence of water from a large, ancient lake. While the presence of clay supports the notion Mars may have once had water, it doesn’t conclusively prove the planet harboured conditions for life.
This animation shows a rotating globe of the new Unified Geologic Map of the Moon with shaded topography from the Lunar Orbiter Laser Altimeter (LOLA). This geologic map is a synthesis of six Apollo-era regional geologic maps, updated based on data from recent satellite missions. It will serve as a reference for lunar science and future human missions to the Moon. Credit: NASA/GSFC/USGS.
After revisiting decades-old data from the Voyager 2 flyby in Jan 1986, NASA scientists have found a shocking discovery. The analysis has revealed a “zigzag” in the magnetic data, just lasting one minute in the Voyager 2’s 45-hour flyby. The zigzag was previously not detected as the data was not analyzed in detail, and just looked at as an overview. Scientists believe that the zigzag represents a plasmoid, a type of structure that was not well understood in 1986.
