There is no danger of waking up one morning to see Jupiter hovering over your head. However, two amazing animations show exactly what this would look like. Astronomer lover Nicholas Holmes creates videos about Space and uploads them to his amazing YouTube channel Yeti Dynamics. One of his creations, which went viral at least several times since its publication in 2013, shows how the planets in our solar system would look if they orbited the Earth from the distance of the Moon. The second video shows slightly different scenarios. Perhaps some of you know that all planets in...
On the night of December 23rd, rain from falling stars awaits us. It is on the eve of the Christmas holidays that the Ursids – the last meteor shower of the year – reach its peak. It has a “modest” intensity – about 10 meteors per hour, so if you are superstitious, it’s time to make a wish list. Ursids are active between December 17-26. Their parent body is the comet 12P / Pons-Brooks, with a period of about 70.7 years. The name of the stream is taken from its radiant point, which is located in the constellation Ursa Minor....
The Мoon is shrinking, causing surface creases and shocks underneath it, AFP writes. Data is from the NASA spacecraft Lunar Reconnaissance Orbiter (LRO), which flies through an elliptical trajectory between 20 and 160 kilometers above the Moon’s surface and takes pictures and other measurements. advertisement A survey of more than 12,000 images indicates that one of the basin at the North Pole of the Moon, considered geologically dead, actually cracks and moves. Unlike the Earth, the moon has no tectonic plates and the only activity is noticeable because of the slow heat loss since it was formed 4.5 billion years...
The rivers on Mars were wider and deeper than those on Earth, according to a publication in the Science Advances Magazine. Up to this conclusion, scientists reached an analysis of 200 dry river beds on the surface of the neighboring planet. Wide and deep rivers have existed on Mars for a surprisingly long period. This makes their disappearance even more mysterious and inexplicable. “We could not explain why there were lakes and rivers on Mars, and the current discoveries make the question even more incomprehensible” writes Edwin Kite of the University of Chicago. ”It turns out that wide and deep...
US Vice President Mike Pens challenged NASA to send people to the Moon by 2024. Jim Bridenstine, NASA administrator, accepted the challenge and announced that the deadline is sufficient. Pens wants a little more dynamics from NASA’s space projects. During a meeting at Alabama Space Center, he announced, that sending astronauts to the Moon, for up to 5 years, is in the goals of the current presidential administration. “Challenge accepted. Now let’s get to work.” Brindenstine said on Twitter. BIG NEWS: President Trump and @VP Pence have directed @NASA to return astronauts to the Moon in the next 5 years.Challenge...
The concept of “day” is so obvious to us, people, that we often get surprised when we realize that the length of the day on other planets can be quite different than here on Earth. Perhaps even more shocking thing is, that so far we did’t know how long is a day on Saturn. Thanks to data collected from the Cassini mission, we have an answer to this long-standing mystery. Saturn spins around its axis for 10 hours, 33 minutes and 38 seconds. The findings are published in the Astrophysical Journal. Planetary scientists often use magnetic fields to determine the...
British and American scientists have proved that billions of years ago the Earth resembled the modern Titan, a satellite of Saturn with an atmosphere and vast seas, high mountains, rivers, dunes, mists. Everything is like Earth’s, but with one difference: the temperature of Saturn’s largest satellite is minus 180 degrees, and rivers and oceans contain hydrocarbons. The results of their research were published in the new issue of the Proceedings of the National Academy of Sciences. According to scientists, 2.4 billion years ago, the Earth’s atmosphere, like Titan’s, contained huge amounts of methane – a gas produced by microorganisms, the...
Recently processed data from NASA’s Galileo orbiter have allowed spectacular video sequences to be produced from the flyby over Jupiter’s Moon Europa. Europa is the sixth natural satellite of Jupiter in increasing order of distance and the smallest of the four Galilean satellites. It was discovered in 1610 by Galileo and named after Europa, the mother of King Minos of Crete and lover of Zeus. Slightly smaller than Earth’s Moon, Europa is composed mainly of silicates and has an icy crust. It has a core that’s most likely made out of iron and nickel. It has a tenuous atmosphere composed of oxygen,...
