NASA probe “touches the Sun” with historic entry into solar atmosphere

After setting off back in 2018 on a history-making mission to study the Sun by getting up close and personal with its atmosphere, NASA’s Solar Parker Probe has entered this region for the first time. The craft’s passage through the Sun’s upper atmosphe… Continue reading NASA probe “touches the Sun” with historic entry into solar atmosphere

Rare Antarctic total solar eclipse to shed light on space weather

A rarely seen total eclipse of the Sun in Antarctica on December 4 is drawing the attention of an international partnership of scientists who hope to learn more about the effects of such eclipses on space weather. The eclipse begins at 0700 GMT and can… Continue reading Rare Antarctic total solar eclipse to shed light on space weather

Parker Solar Probe sets new distance and speed records on solar slingshot

NASA’s Parker Solar Probe has set a new pair of records after it survived its 10th close encounter with the Sun. On November 21, 2021 at 4:25 am EST (08:25 GMT), the robotic deep-space explorer came within 5.3 million miles (8.5 million km) of the Sun’… Continue reading Parker Solar Probe sets new distance and speed records on solar slingshot

Dark matter detector may have accidentally detected dark energy instead

Last year, physicists reported that an experimental dark matter detector picked up a strange signal that could hint at new physics, with several suspects highlighted. Now, Cambridge scientists have proposed an answer that wasn’t considered at the time … Continue reading Dark matter detector may have accidentally detected dark energy instead

Magnetism, not cataclysm may be the cause of Mercury’s giant iron core

Mercury’s disproportionately massive core may be the result of the Sun’s powerful magnetic influence rather than the consequence of a cataclysmic collision with another body in the ancient past, according to the results of a new study.Continue ReadingC… Continue reading Magnetism, not cataclysm may be the cause of Mercury’s giant iron core

Extreme space weather could soon pose a larger risk to Moon missions

A recent study has revealed that crewed missions launching to Earth’s moon and beyond may soon be facing a new challenge. Just five years from now, such ventures could be at an increased risk of extreme space weather events emanating from the Sun.Conti… Continue reading Extreme space weather could soon pose a larger risk to Moon missions

Voyager 1 detects plasma “hum” in interstellar space

More than 40 years after launch, Voyager 1 is still making new discoveries. The latest achievement by the craft is the detection of a faint, plasma “hum,” indicating that there may be more activity in interstellar gas than previously thought.Continue R… Continue reading Voyager 1 detects plasma “hum” in interstellar space
