NGC 4747

It's nearly impossible to reach the Sun because you inherit the Earth's inertia when you leave Earth. This means you're going at least as fast as the Earth's orbital velocity, which is 67,000 miles per hour (108,000 kilometers per hour), so you need to slow down. In the frictionless vacuum of space, it takes just as much energy to decelerate as it does to accelerate, so it takes the same amount of fuel to go from 67,000 MPH to zero as it does to go from zero to 67,000. NASA managed to get the Parker Solar Probe to the Sun by using using gravity from Venus to "tug" it in the direction opposite of Earth's orbit to slow it down. It took seven passes by Venus to accomplish this, orbiting the Sun 24 times. The whole process took seven years. It still didn't really reach the Sun, but now has a highly irregular orbit in which it passes close (in astronomical terms), and the Sun's gravity accelerates it so much that it gets flung back out to the orbital distance of Venus by the slingshot effect before returning. During those close passes, it becomes the fastest man-made object ever made, reaching speeds of 430,000 MPH (692,000 KPH).

DID YOU KNOW: The Moon is about 400 times smaller than the Sun… yet it also happens to be almost exactly 400 times closer to Earth. This incredible coincidence makes the two appear nearly identical in size in our sky

Captured this with my telescope in 30 minutes last night from my back yard in Los Angeles using the Unistellar EVscope . This supernova is in a galaxy 50 million light years away. So the light you’re seeing is from 50 million years ago!

@stadtlandlyrik Ihr könnt auch länger gucken...

Guckt mal alle kurz in den Himmel. Der Mond ist wunderschön. Immer. Aber heute Nacht ganz besonders.

🚨: People don't realize that we are the first generation in the history of our species to see a sunset on another planet. This is a real photo of sunset on Mars.

15 Minuten Video,ab 3:30 min kommt ein Kondensstreifen von einem Flugzeug ins Bild.

Mit dem Seestar S30/ Mond.

Mond heute unglaublich hell, und groß.Gibt ein paar Schleierwolken.

I’ve been seeing this photo posted all over the last few days from other accounts so I thought I’d share it again! This is a Falcon 9 rocket transiting our sun, I captured this with a specially modified telescope 😎 Later today I’m capturing the heavy variant of this vehicle 👀

Der an der Ostseeküste gestrandete Wal ist mit einer Transport-Barge in dänischen Gewässern angekommen. Der Umweltminister Mecklenburg-Vorpommerns, Till Backhaus, erklärte am Mittwoch in einer Pressekonferenz, der Wal liege ruhig und habe in der Nacht auch vokalisiert. „Das heißt, es geht ihm gut“, so Backhaus. „Wir gehen davon aus, er wird in der Nordsee dann freigelassen. Der Standort ist jetzt in Abstimmung. Er wird dann weiter beobachtet.“ Holt euch Bilder von Timmy nach Hause und unterstützt unseren qualitativen Journalismus!
