General Discussion / Nasa makes history with closes...
Last post by Jason - January 05, 2025, 12:14:04 AMOn December 27, 2024, the Parker Solar probe made its closest approach to the sun at 3.8 million km. It doesn't sound that close, but look at it this way. The Sun is 1.4 million km in diameter so the probe was less than three solar sizes away.
On Christmas Eve it entered the Sun's outer atmosphere, the corona. Bizarrely, the corona is hotter than the surface of the sun reaching many millions of degrees. The probe survived despite its outside temperature reaching 980 C. It was moving at a speed of 692,000 km/h. That's like going from London to New York in less than 30 seconds.

Last post by Jason - January 04, 2025, 11:24:28 PMDid it happen, Bill? Is it still bright or has it likely diminished by now? I remember a star that went nova hundreds of years ago and it was reportedly so bright that it cast a shadow. I think it was still bright for maybe a year.
I had no idea that stars could go nova more than once. I thought one poof and that was it! Fascinating! Maybe I'll still be around for the next round.

Last post by buster - January 03, 2025, 10:05:40 AMThe popularity of this story is still a mystery. It went from ordinary reception to tops in views for the whole site in less than a year. It's well in the lead with over 63,000 views. Overnight was huge, garnering 138 views in 10 hours, which averages to faster than one view every 5 minutes.
I read a few parts and it is funnier than I remembered. But...
My pseudo-daughter in law doesn't care about the story, but being a sports fan, is totally engrossed in the numbers. She might text, "How'd we do over the weekend?"
Be thankful for small mercies, as my mother always said. But it would be nicer if she actually read it.
I'm pretty sure she can read, but she does live in the country that elected Trump.

The daylight hours are getting longer, now. :-)"
And, as most know, but not all do, the sun climbs a bit higher in the sky each day, and so provides more brightness and heat, though the air temp wont change for a few months.

And that means no skiing on the wilderness trails.

A good article about a star near the constellation of Corona Borealis that is expected to brighten to be visible to the unaided eye, in the next few days.
This happens about every 80 years and will only be bright for a few days.
This was in the news last Spring and it was suppose to brighten by last September.
Unfortunately with the cloudy weather we have at this time of year, I don't expect anyone in this area to be about to see any stars in the night sky. :-(
