The Hottest Planet Ever

NASA is launching a mission to send a probe into the sun, and it's the first to be named after a living scientist: Eugene Parker and the Parker Solar Probe! Astronomers have found another hot topic, and it's the hottest planet we've ever seen at 4300°C!

"Looking forward to being dead when that happens."
I'm going to tell my children that when I am older.

"Dr. Parker, in recognition of your immense contributions to science, we hereby honor you with this eponymous probe so that we may symbolically launch your legacy into the goddamn Sun. It's gonna be SICK."

I am very upset that this probe isn't named Icarus :(

[kcwidman]

Why would NASA send a probe to the sun during the summer? It will be too hot then.

[erick]

Wow, the future of science looks really bright. I think we're getting warmer on our search for the truth.

[godzilla]

Good thing that NASA named the probe and not the internet. Otherwise we'd be sending Probey McProbeface into the sun.

Idk what they're talking about, my Corona stays at a cool 40° F 😎

In 300 million years, these radioactive puns will never decay entirely.

[tgxkfinn]

I came for the puns. I was not disappointed.

It the Parker solar probe shaped like a Parker square?

It does make sense that corona is hotter than surface, because amount of light emitted by surface, and light that passes through corona is more or less the same, corona is far less dense. So let's say that Sun emits E amount of energy, and corona absorb f.e. 0.1E of energy, but it has only lets say 0.01 of effective mass of Suns surface. Then per unit of mass corona need to emit 10 times more energy than Sun surface. And to emit more energy you need higher temperature. Of course, it is rough, quick estimation, but it does make sense.

The probe should be just fine when it hits the sun, as long as they time it to hit the sun at night.

Earth is the hottest planet, because I live here

[starpravesh]

I was wondering what happened to Peter Parker. Cheeky guy thinks changing him first name to Eugene will disguise his secret spiderman adventures.

[empoleonmaster]

I forget where I heard this, it was either discovery channel or history channel YEARS ago, and in it some scientist theorized that the reason the corona of the sun was so hot was the sound traveling through the sun.

[mynameismatt]

Hank is turning in to John with all "inevitability of death" talk recently.

[RitobanRoyChowdhury]

Let's hope they don't make a Parker square out of it! Parker square jokes? Anyone?

[Vidiri]

.."I look forward to being dead when that happens" That's what I sarcastically think about every cool space thing that the future will be able to participate in

[dyalanbrain]

launch at it at night while the sun is off.

[linuxdragon]

Big mood when Hank said, "Looking forward to being dead when that happens."
