The first survey data from the 600-megapixel Euclid space telescope is available now. Euclid observed 26 million galaxies in total in just one week. Watch this report for more details!

Telescope's first survey finds 26 million galaxies in 1 week

<p>Astronomers have identified the nearest known Einstein ring, a rare gravitational lensing phenomenon where light from a distant galaxy is bent by the gravitational field of a closer galaxy. Initially thought to be a single galaxy, the object was first observed more than a century ago but has now been confirmed as a gravitational lens.</p>
<p>Such galactic lenses were predicted by Albert Einstein in 1936 as part of his general theory of relativity. At the time, he believed they would be too difficult to observe. However, with modern telescopes, such phenomena can now be detected. &ldquo;It was there all along, but we had no idea,&rdquo; said Thomas Collett from the University of Portsmouth, UK.</p>

<p>The Einstein ring was discovered when Collett and his team studied NGC 6505, an oval-shaped galaxy located around 600 million light-years from Earth. The galaxy, first documented in 1884, was found to be bending the light from a second galaxy approximately 6 billion light-years away.</p>

Breathtaking! Euclid telescope reveals first images from massive 3D map of universe

<p>In a stunning discovery, seven new rogue planets were identified by the Euclid space telescope which shed light on the mysteries of such dark, starless worlds which are freely floating in the universe.&nbsp;</p>

<p>Unlike planets which revolve around the stars, such rogue planets do not go through days or years and continue to exist in perpetual night.&nbsp;</p>

<p>Even though these rogue planets are isolated, scientists now think they are capable of hosting life. According to the researchers, trillions of rogue planets are present in the Milky Way.</p>

<p>In the first scientific results of the European Space Agency on Euclid's mission, it was mentioned that seven new free-floating gas giants are present in the universe, each of them being four times the mass of Jupiter.</p>

<h2><strong>Rogue planets with a habitable zone?</strong></h2>

<p>Astronomer at&nbsp;Queen Mary University of London Gavin Coleman, who was not among the researchers, spoke about the fascination with these rogue planets.&nbsp;</p>

<p>“We’ve all grown up with the sun in the sky, and so to think of a planet just drifting through space with no star on its horizon is fascinating,” he said.</p>

<p>As per the scientists, not all rogue planets are known to remain alone. Some are binary systems in which two planets orbit each other.&nbsp;</p>

<p>The rogue planets' potential&nbsp;habitability&nbsp;has significant implications in the hunt for extraterrestrial life. “Some of our closest neighbours are likely rogue planets,” said Martin.&nbsp;</p>

Euclid telescope sends stunning test pictures back home from space. Have a look

<p>Euclid, a groundbreaking space telescope named after the Greek mathematician Euclid, has embarked on an extraordinary million-mile journey from Florida as it sets out to unravel the mysteries of the universe. This two-tonne probe, part of a $1 billion European Space Agency mission, was launched into space aboard Elon Musk's SpaceX Falcon 9 rocket from Cape Canaveral at (11:11 AM local time) or 8:41 PM IST.</p>

<p>The telescope will be dispatched to an observing position 1.5 million kilometres away from Earth.</p>

<h2><strong>What's the objective of the mission?</strong></h2>

<p>The primary objective of Euclid is to observe and study the large-scale structure of the Universe.
