The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second) If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. Thanks to the work of Albert Einstein and others, we now understand light speed to be a theoretical limit: light speed — a constant called “c” — is thought to be not achievable by anything with mass. Is the speed of light really constant?Light travels in waves, and, like sound, can be slowed depending on what it is traveling through. Let’s Start A new...
Jupiter is not only the biggest planet in the Solar System. A new study of astronomers from Laurence Livermore’s Californian Laboratory, and the University of Munster in Germany, defines Jupiter as the oldest planet in the solar system, Space.com reports. The new analysis of the Planet calculates that the core of Jupiter was 20 times larger than the Earth only 1 million years after the formation of the Sun. This is a fairly short time because young stars usually throw a lot of energy in their first years, which is enough to blow dust and gas to prevent the formation...
Astronomers have revealed details of mysterious signals emanating from a distant galaxy captured by a telescope in Canada. The exact nature and origin of the radio waves are unknown, the BBC writes. Among the 13 fast radio bursts, there was also a very unusual repeating signal, coming from the same source at a distance of about 1.5 billion light-years. Such an event was reported only once before by another telescope. Ingrid Stears, an astrophysicist at the University of British Columbia, says, “Knowing that there was such a thing before, we supposed there were such things somewhere. With more repeaters and more...
If the sun appears a bit more intense than normal to you this week, you have a keen eye. The Earth has just made its closest approach to our nearest star for the year. The orbital milestone is known as “perihelion,” and it marks the time when the distance between the Earth and the Sun is at its smallest. The event occurs every year in early January, and in 2019 it took place Thursday, Jan. 3 at 12:20 a.m. EST (or at 05:20 GMT, depending on your time zone). On average, the Earth orbits the Sun at a distance of...
The new 2019 arrives with the promise of spectacular events that will make lovers of astronomy to stare to the night sky. The “Meteor showers” Perseid and Geminid invariably present impressive celestial performances, but there will be other astronomical events during the year that are worth watching, according to Gizmodo website. In 2019, lovers of the night sky will witness a total eclipse of the Sun, three partial Solar eclipses, three super Moons – on January 21, February 19 and March 21, complete and partial lunar eclipse, a rare transit (passage) of Mercury in front of the Sun. The rare...
NASA’s OSIRIS-REx spacecraft just barely reached its goal – the asteroid Bennu, but has already made significant discoveries. One of them is that there is water inside the asteroid, the space agency said. The data of the device show that in the structure of Bennu there are molecules of oxygen and hydrogen that are connected to each other. Scientists say they are abundant in the clay minerals of the asteroid. This means that at some point in its story, Bennu had a touch of water. The asteroid itself is too small to have ever had liquid water. But such was...
The Parker Spacecraft has successfully passed its first approach to the Sun, NASA reported. This happened on Monday 5th of November, when the device flew 24 million kilometers from the surface of the Star. This makes Parker the only spacecraft that was so close to the Sun. 24 million km. look very much from Earth’s point of view, but for the scale of the Sun and Space is very small. They have exposed Parker to serious heat, strong solar radiation and a solar wind. “The Parker Probe is designed to be able to take care of itself while approaching the...
Probably you have never think the astronauts will bring to Space some of the following items. For some of you they might be strange, for others weird, but for more of us they are simply inspiring! 1.Martian rovers “Spirit” and “Opportunity” are equipped with historical protective fittings – made of metal remains of the World Trade Center in New York, destroyed in the terrorist attacks on September 11, 2001 2.About the year 1607, the British colony Jamestown was founded in America. 400 years later the Atlantis shuttle carries a plaque with the name of the city, waiting for its glory time...
