Nasa's Parker Solar Probe makes history with closest ever approach to Sun
Parker Solar Probe made closest approach to Sun on Dec 24.
Launched in 2018, it's completed 21 solar flybys.
Mission aims to study Sun's corona and solar wind
On December 24 at 6:40 am Eastern time, the spacecraft flew just 3.8 million miles from the Sun’s surface, breaking its own record and getting more than seven times closer than any previous mission, according to Space.com.
During the flyby, the probe travelled at a breath-taking speed of 430,000 miles per hour, making it the fastest man-made object ever
Dr. Jenifer Millard, an astronomer at Fifth Star Labs, pointed out the long-standing puzzle: “The surface of the Sun is about 6,000°C, but the corona, this tenuous outer atmosphere, reaches millions of degrees.”
Parker’s mission is vital for understanding space weather and its potential impact on Earth. After its flyby, the spacecraft will be out of contact with Earth for several days, and scientists will anxiously wait for a signal on December 27 to confirm it survived the extreme conditions.
That's all for this news
