China’s Mars Mission Took This Picture of the Earth and Moon No matter where you are, where you’ve been and where you’re going, it’s always good to see home.  And we all love seeing pictures of our home planet, as seen from space. The latest image of the Terran System comes from China’s Mars mission, Tianwen-1, which launched on July 23. It captured an image of … Continue reading “China’s Mars Mission Took This Picture of the Earth and Moon” The post China’s Mars Mission Took This Picture of the Earth and Moon appeared first on Universe Today.

Earth Observation Satellites Could be Flown Much Lower than Current Altitudes and Do Better Science Satellite engineers know what every photographer knows: get close to your subject to get better pictures. Not just visible light pictures, but all across the spectrum. The lower altitude also improves things like radar, lidar, communications, and gps. But when your subject is Earth, and Earth is surrounded by an atmosphere, getting closer is a … Continue reading “Earth Observation Satellites Could be Flown Much Lower than Current Altitudes and Do Better Science” The post Earth Observation Satellites Could be Flown Much Lower than Current Altitudes and Do Better ScienceRead More →

Astrophysicists observe long-theorized quantum phenomena At the heart of every white dwarf star—the dense stellar object that remains after a star has burned away its fuel reserve of gases as it nears the end of its life cycle—lies a quantum conundrum: as white dwarfs add mass, they shrink in size, until they become so small and tightly compacted that they cannot sustain themselves, collapsing into a neutron star. phys.org Go to SourceRead More →

ALMA finds possible sign of neutron star in supernova 1987A Two teams of astronomers have made a compelling case in the 33-year-old mystery surrounding Supernova 1987A. Based on observations of the Atacama Large Millimeter/submillimeter Array (ALMA) and a theoretical follow-up study, the scientists provide new insight for the argument that a neutron star is hiding deep inside the remains of the exploded star. This would be the youngest neutron star known to date. phys.org Go to SourceRead More →

Stunning space butterfly captured by telescope Resembling a butterfly with its symmetrical structure, beautiful colors, and intricate patterns, this striking bubble of gas—known as NGC 2899—appears to float and flutter across the sky in this new picture from ESO’s Very Large Telescope (VLT). This object has never before been imaged in such striking detail, with even the faint outer edges of the planetary nebula glowing over the background stars. phys.org Go to SourceRead More →

Perseverance Rover Rumbles Off the Launchpad to Mars NASA’s Mars 2020 Perseverance rover is now successfully on its journey to Mars, launching from Space Launch Complex 41 at Cape Canaveral Air Force Station at 7:50 am EDT (1150 GMT). Just minutes before the Atlas 5 rocket rumbled off the launchpad, a 2.9 magnitude earthquake rumbled out in California, giving a minor shake to … Continue reading “Perseverance Rover Rumbles Off the Launchpad to Mars” The post Perseverance Rover Rumbles Off the Launchpad to Mars appeared first on Universe Today.

There’s a flash of ultraviolet just as a white dwarf is exploding as a supernova Astronomers recently spotted a rare type of supernova explosion that was accompanied by a massive flare of ultraviolet radiation. Untangling the mystery of the UV flash could help unravel the mysterious nature of these supernova explosions, and even help us understand the age of the universe. Enjoy Some Ultraviolet It doesn’t have a pretty name, … Continue reading “There’s a flash of ultraviolet just as a white dwarf is exploding as a supernova” The post There’s a flash of ultraviolet just as a white dwarf is exploding as a supernovaRead More →

Outburst of the X-ray transient MAXI J1727–203 investigated with NICER Using the NICER instrument, astronomers have conducted a detailed X-ray spectral and variability study of an outburst from an X-ray transient source known as MAXI J1727-203. Results of this investigation could shed more light on the true nature of this source. The study is detailed in a paper published July 22 on arXiv.org. phys.org Go to SourceRead More →

A Group of Meteorites All Came From a Destroyed Planetesimal With a Magnetic Core Before our Solar System had planets, it had planetesimals. Scientists think that most of the meteorites that have struck Earth are fragments of these planetesimals. Scientists also think that these planetesimals either melted completely, very early in their history, or that they remained as little more than collections of rocks, or “rubble piles.” But one … Continue reading “A Group of Meteorites All Came From a Destroyed Planetesimal With a Magnetic Core” The post A Group of Meteorites All Came From a Destroyed Planetesimal With a Magnetic Core appeared first onRead More →

Thanks to Cosmic Radiation, There Could be Life on Mars, Just a Couple of Meters Under the Surface Remember back in 2008 when the Phoenix lander on Mars scraped away a few inches of rust-colored regolith to reveal water ice? Or in 2009, when Mars Reconnaissance Orbiter observations revealed vast areas of subsurface ice, event at low latitudes? These findings – and many more like them – indicate there’s a lot of interesting … Continue reading “Thanks to Cosmic Radiation, There Could be Life on Mars, Just a Couple of Meters Under the Surface” The post Thanks to Cosmic Radiation, There Could be Life onRead More →

Astronomers pinpoint the best place on Earth for a telescope: High on a frigid Antarctic plateau au, could offer the clearest view on Earth of the stars at night, according to new research by an international team from China, Australia and the University of British Columbia (UBC). The challenge? The location is one of the coldest and most remote places on Earth. The findings were published today in Nature. phys.org Go to SourceRead More →

Discovered: Remnant of ancient globular cluster that’s ‘the last of its kind’ A team of astronomers including Carnegie’s Ting Li and Alexander Ji discovered a stellar stream composed of the remnants of an ancient globular cluster that was torn apart by the Milky Way’s gravity 2 billion years ago, when Earth’s most-complex lifeforms were single-celled organisms. This surprising finding, published in Nature, upends conventional wisdom about how these celestial objects form. phys.org Go to SourceRead More →
