"New Horizons" approached Pluto at a distance of 12.5 thousand kilometers. For comparison: satellites in geostationary orbit "hang" above the Earth at a distance of 36 thousand km, which is almost 3 times further

The device spent 9.5 years on the road and flew about 5 billion km. With such a scale of travel, the accuracy of the "hit" is amazing

2022-06-16 17:00:03 Animation of the lunar eclipse

During an eclipse (even a full one), the moon does not disappear completely, but turns dark red. This is due to the fact that the Moon, even in the phase of a total eclipse, continues to be illuminated. The sun's rays passing tangentially to the Earth's surface are scattered in the Earth's atmosphere and due to this scattering partially reach the Moon.

Since the earth's atmosphere is most transparent to the rays of the red-orange part of the spectrum, it is these rays that reach the surface of the Moon to a greater extent during an eclipse, which explains the color of the lunar disk. In fact, this is the same effect as the orange-red glow of the sky at the horizon (dawn) before sunrise or immediately after sunset.

It's creepy. The only hope is that they are being collected back at the other end.

2022-06-15 13:00:01 Where is planet Earth located in the universe?

The Earth is the third planet from the sun within our Solar System.

Our solar system is located in the Orion Spiral Arm of the Milky Way Galaxy about two-thirds of the way out from the center.

The Milky Way galaxy is found among a group of galaxies known as the Local Group - an area of around 10 million light-years wide. The exact number of galaxies in the local group is unknown.

The Local Group is in the Virgo Supercluster, an enormous collection of more than a million galaxies that stretches across a region of space 110 million light-years across. The Virgo Supercluster is one of about 10 million superclusters in the observable universe.

And in the large-scale structure of the universe where the bright areas represent huge collections of galaxies, the Virgo Supercluster exists in one of the dark cosmic voids.

2022-06-14 16:00:03 Meet one of the most powerful rockets in the world. The Delta IV Heavy rocket.

Video shows DeltaIV taking off last week from Space Launch Complex 6 at Vandenberg Air Force Base in California — Generating 2.1 million pounds of thrust — the equivalent of 51 million horsepower — the hydrogen-fueled engines quickly propelled the rocket skyward, consuming 5,000 pounds of liquid hydrogen and oxygen propellants per second as it arced away on a southerly path over the Pacific Ocean.

2022-06-14 13:00:03 If the universe is expanding, then what's it expanding into? What's on the other side? Does the universe even have an edge?

All of the distant galaxies in the universe are moving away from each other. But there is no center they are expanding from. And every region of space is being stretched.

Think of a balloon and as it inflates, the surface stretches. Every point on that surface moves away from every other point. A tiny being could walk on the expanding balloon forever and never find the edge. For the tiny being, the balloon is everything.

If OUR universe is everything, then it isn't expanding into anything. It's just expanding. Nothing may be on the other side except the realm of misconceptions.
