Super excited for this!
@ESASolarOrbiter is carrying our@USNRL "SoloHI" camera - an instrument very much like (nearly identical to) our WISPR camera that's returning amazing images from#ParkerSolarProbe!

Here's comet 29P/Schwassmann-Wachmann (center) on Feb 2. 29P just had a 4-mag outburst a few hours earlier, its largest since 2015. And of course, whenever you are taking an image a satellite will pass over your target so you have to take another one...pic.twitter.com/ZkcCz4VLSe

A slew of
#ParkerSolarProbe papers were released in an Astrophysical Journal Supplemental today: https://iopscience.iop.org/issue/0067-0049/246/2 … Some of them are open access, and hopefully most of the others are on arXiv... (I know at least one of them is!

It's ALIIIIIIIVE!!!!! PSP ain't afraid of no measly 1200f temperatures

Can't wait until we get our data down from the spacecraft now! (There'd better be a comet in there this time...)https://twitter.com/JHUAPL/status/1223601026445369345?s=19 …

We know our sun is surrounded by a great bubble-like heliosphere that sets our solar system apart from the rest of interstellar space. The European Space Agency's Solar Orbiter - aka SolO - is due to launch in February. Read more and watch a video http://bit.ly/3aSMp7o pic.twitter.com/QASY0Ma9xu

This is the sharpest movie of the Sun ever made. Even at this fine resolution, the scale is enormous; each plasma cell here is about the size of Texas. https://www.nso.edu/telescopes/dkist/first-light-cropped-field-movie/ … via

Parker Solar Probe, Solar Orbiter next week, and now DKIST. Fun times for solar physics!https://twitter.com/Astro_Jonny/status/1222590359970119681 …

#ParkerSolarProbe made its 4th close approach to the Sun early this morning and set new records in the process! Parker flew about 11.6 million miles from the Sun and achieved a top speed of more than 244,000 mph, breaking records it set in 2018: https://blogs.nasa.gov/parkersolarprobe/2020/01/29/parker-solar-probe-completes-fourth-closest-approach-breaks-new-speed-and-distance-records/ …pic.twitter.com/rYaXgI5o84Hvala.

[4/4] PSP's anticipated peak velocity in 2024 is about 200km/s, so even then the relativistic effects won't be significant. Alas, time flies just as fast for PSP as it does for us (which is probably a good thing when you're being cooked just a few million miles from the Sun!)

[3/n] ...0.00036c translates to a time dilation of 99.99999999999352% (i.e. time is veeeeeeeeery slightly slower as experienced by PSP). How much slower? If my math is correct*, a year would be about 10 milliseconds longer for PSP. (*I have zero doubt I'll be corrected if not)

[2/n] At peak on this encounter, PSP will be going at ~109.2km/s, which is 0.036% of c. Relativistic effects (time dilation) only get noticeable at about 0.1c (10% of c). The effect is exponential as you move faster, so PSP's 0.00036c doesn't really register much. Nonetheless...

[1/n] I've had a few folks ask me if
#ParkerSolarProbe will experience any relativistic effects given how fast it's moving. Here's a short thread on that...pic.twitter.com/zbda7ynFRk

#ParkerSolarProbe is now less than 12 million miles (~19 million km) from the solar surface, traveling at over 240,000mph! We're less than 24hrs from perihelion, so hopefully all is well behind that 1,100f heat shield. [screenshot via@JHUAPL, http://parkersolarprobe.jhuapl.edu/ ]pic.twitter.com/OkPDZ2aSu0

#ICYMI we're now looking at two-hour launch window for@ESASolarOrbiter opening on 7 February (23:15 EST) / 8 February 04:15 GMT (05:15 CET). Download our media kit here

Hot, hot, HOT! And fast! Wow. And it'll keep getting hotter and faster for 2 more days before backing off again. Hopefully our
@USNRL WISPR camera is getting lots of pretty pics out there!
