In Search of Alien Planets in the Universe Documentary - Explore the Universe and Planets Scientists already know about a vast number of exoplanets, or worlds beyond our solar system: telescopes have helped us catalogue thousands already, with many more to come. But it is far more difficult to know what conditions might be like on those planets, since they are so different. In order to narrow that down, the researchers behind the new study combined a variety of data to understand how habitable planets around M dwarf stars – which make up 70 per cent of those in our galaxy – might be. Planets around M dwarf stars are thought to be the most likely place for us to find alien life, because they are so common and therefore easier to find. The study helped them redefin...

THIS IS THE MOST DANGEROUS ASTEROID DETECTED ➥ Telegram - https://t.me/kosmo_eng ➥ Subscribe - http://bit.ly/SubbKosmo If an object measuring 1 km across were to hit our planet, the consequences would be much graver. There were precedents in the history of our Earth and there is no guarantee it will not happen again. Over a thousand celestial bodies are posing a potential threat today. So what would happen if a really large asteroid were to collide with us? #ASTEROID #Earth #Kosmo

Here’s Why Zodiac Constellations Are Still Used in Astronomy To understand astronomy, astrology might actually not be a bad place to start... Although scientists certainly haven’t proven that being an Aries makes you more impatient or a Libra means you’re wise, the constellations in the zodiac have unlocked hidden secrets of the stars for centuries. In this episode, we’ll explore the ecliptic line and how it is still significant to astronomers today. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Visit our shop at http://shop.seeker.com Here’s how it works. If you could see all of the stars during the day, over the course of a year you’d be able to see the Sun slowly moving along a path from one constellation to the next. That imaginary path is called the ...

Physicists May Have Found Dark Matter: X-rays Surrounding “Magnificent 7” May Be Traces of Theorized ParticleAn artistic rendering of the XMM-Newton (X-ray multi-mirror mission) space telescope. A study of archival data from the XMM-Newton and the Chandra X-ray space telescopes found evidence of high levels of X-ray emission from the nearby Magnificent Seven neutron stars, which may arise from the hypothetical particles known as axions. Credit: D. Ducros; ESA/XMM-Newton, CC BY-SA 3.0 IGO Researchers say they may have found proof of theorized axions, and possibly dark matter, around a group of neutron stars. A new study, led by a theoretical physicist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called...

The Inner Secrets of Planets and Star - Formation of the Solar System Documentary In the beginning - before the 1920s, these words had no place in our scientific understanding of the universe. Astronomers believed the cosmos to be eternal and unchanging. We knew of only one galaxy and a few million visible stars, and this was the scope of our observable universe. Then astronomer Edwin Hubble observed, courtesy of redshift, distant galaxies speeding away from each other and formulated Hubble's Law to explain the universe's uniform expansion. Redshift just refers to a distant celestial body's shift toward longer, or redder, wavelengths, compliments of the Doppler effect.
