FYI NASA just lobbed its Parker probe around the Sun in closest flyby yet: A nerve-racking 15M miles from the surface

NASA’s Parker Solar Probe has kept its cool, successfully surviving sweltering temperatures to reach its first close encounter with the Sun, coming within 15 million miles of the solar surface. Launched in August, the spacecraft is on a mission to study the star at the center of our Solar System. The goal is to help scientists …

Fruit flies use the power of the sun to help them fly in straight lines

Fruit flies may have tiny brains about as big as poppy seeds, but their noggins are complex enough to the remember the Sun’s position to help with navigation, according to a new study in the journal Current Biology. Without these special compass cells in their brain fruit flies, known as Drosophila, would end up flying …

The Solar System's oldest minerals reveal the Sun's violent past

An analysis of hibonite, thought to be among the oldest minerals in the Solar System, has shown the turbulent and violent early history of our sun. A team of scientists analysed meteorite samples containing hibonite using a scanning electron microscope and a mass spectrometer. The mineral contains small pockets of inert gases …

Alien sun has smashing time sucking up planets

Scientists believe they have captured direct evidence of a star feasting on its own planets for the first time. RW Aur, a binary star system located in the Auriga constellation 450 light years from Earth, has long puzzled astronomers. The light from one of its stars, RW Aur A, repeatedly dims and flickers back to life every …

The Sun will blow up into a huge, glowing bubble of gas during its death

The Sun will shed a large chunk of its mass to turn into a planetary nebula, a gigantic globe of luminous gas, as it nears the end of its life cycle. Low mass stars like the Sun will become red giants and then white dwarves when they die. Now, a paper published in Nature Astronomy predicts that in between those stages, the Sun …

Sun's core in a real spin, but you wouldn't know just by looking at it

Our Sun's core is rotating four times faster than its surface. That's the conclusion boffins have reached after peering at data from the joint NASA-ESA SOHO (Solar and Heliospheric Observatory) mission, first launched in 1995 and still turning in the science. What SOHO found is something solar scientists have been trying to …

You wait ages for a sun, then two come along at once: All stars have twins, say astroboffins

Nearly all stars, including our Sun, are born from hot, dense molecular clouds and come in pairs, according to a paper to be published in the Monthly Notices of the Royal Astronomical Society. Binary star systems are common in space. It was estimated that up to 80 per cent of massive, bright O‑type and B‑type stars are locked …

Our Sun's been using facial scrub: No spots for two weeks

NASA's Solar Dynamics Observatory has spotted nothing for the last two weeks, which is unusual. By “nothing” we mean no Sunspots, the magnetic fluctuations that cause the Sun to form dark spots that produce flares of star-stuff that can rise millions of kilometres into space. Big ones could swallow the Earth, with room left …

Ten-trillionths of your suntan comes from intergalactic photons

Astronomers led by the International Centre for Radio Astronomy Research (ICRAR) in Australia have calculated that ten trillionths of your suntan comes from beyond our local galaxy. Professor Simon Driver, lead author of the research, published today in The Astrophysical Journal, said that each square metre of the Earth is …

What's DriveScale up to? Mix-'n'-match server and disk storage, for starters

Backgrounder DriveScale is a startup that emerged from a three-year stealth effort earlier this year with hardware and software to dynamically present externally connected JBODS to servers as if they were local. The idea is to provide composable server-storage combos for changing Hadoop-type distributed workloads. It is meant to share the …

Sic transit Mercury Monday

Mercury will transit the Sun today between 11:12 GMT (7:12 AM EDT, 12:12 BST) and 18:42 GMT (2:42 PM EDT; 19:42 BST), with NASA TV offering a live feed from its Solar Dynamics Observatory (SDO). The space agency has full details on its coverage of the event here. The European Space Agency (ESA) will also be catching the action …

Mercury to transit Sun: Viewer discretion advised

Mercury will transit the Sun next Monday, and those wishing to witness this occasional event without risking blindness will be pleased to know that NASA will have full coverage. The planet will creep across the Sun's fiery surface between 11:12 GMT (7:12 AM EDT, 12:12 BST) and 18:42 GMT (2:42 PM EDT; 19:42 BST). The entire …

Blocking out the Sun won't fix climate change – but it could buy us time

The Paris climate talks hope to set out how we can reduce the amount of carbon we’re pumping into the atmosphere. But emissions cuts alone may not be enough. Atmospheric CO2 is the blanket that keeps our planet warm and any further emissions will mean more global warming. Observations in recent years show that warming is …

SOHO solar scope spies 3000th 'sungrazer' comet

One Worachate Boonplod of Thailand has been honoured as the person who spotted the 3,000th comet revealed to date by the Solar and Heliospheric Observatory (SOHO). The 3,000th comet spotted by SOHO. Pic: NASA Comet 3,000 ahoy. Pic: ESA/NASA SOHO was launched in 1995 to observe the Sun's atmosphere and solar wind. Although …
