Astronomers have discovered a mind-bending structure a colossal ring of galaxies which are behaving differently. The filament of matter stretches 50 million light-years, and contains a row of galaxies 5.5 million light-years long. Astronomers say that it defies the cosmic laws that shape the universe.
Is our understanding of space about to change forever?

Universe Breaks It's Own Rules: The Cosmic Giant That Shouldn't Exist

Voyager 1, over 13 billion miles away, what if it detect signals from 11 light-years distant stars like Ross 128. While the source may be natural or human-made, such signals fuel the search for extraterrestrial life. 

What if Voyager detected a signal 11 light-years away from Earth?

Voyager 1 is over 13 billion miles from Earth and would take 23 million years to reach the Orion Molecular Cloud, a star-forming region 1,300 light years away. Know about this cosmic distance and Voyager’s mission. Read more below.

An Earth-sized world was found just 22 light-years away,&nbsp;orbiting around a small red dwarf star.

Discovered by scientists in the US, this Earth-sized world is the closest to our Solar System. 
 
The exoplanet has been named LTT 1445 Ac and it is some 1.37 times the mass and around 1.07 times the Earth's radius.

The planet is too hot for the existence of life, however its similarity with our Earth makes it a good option to understand how planets evolve, and what factors make an Earth-like world different from another such planet. 
 
The scientists used data collected by the TESS exoplanet-hunting telescope in 2021 to first identify LTT 1445 Ac.

But they faced some difficulties in observing it, which meant the astronomers could not be certain of its properties.

The exoplanet exists in a different system. The star this planet orbits is one of the three stars, which is gravitationally bound in a trinary system. The scientists observe the changes in the light of the host star to find and study exoplanets, however, in systems of stars, the stellar companions also leave an effect on the other stars' light.

<h2>How do scientists understand the properties of an exoplanet?</h2>

Two types of measurement are needed to understand an exoplanet's properties. The first is transit data which is the tiny dips in starlight which occur after an orbiting exoplanet passes between the star and the Earth. 
 
The second measurement is radial velocity data which measures the amount of gravity tugs of an exoplanet on the star by recording changes in the starlight's wavelength as it very minutely wobbles on the spot.

The transit data informs the scientist of an exoplanet's radius which can be calculated from the amount the light of the star which dims during a transit. The radial velocity data informs the scientists about the mass of the exoplanet. 
 
The mass and radius combined together tell us the exoplanet's density and using that the scientists understand what the exoplanet is made of. 
 
If the planet is found to have low density it implies it has lost of atmosphere and is like a gas giant. A higher density means it has a rocky composition, like Earth, Venus, Mars, or Mercury.

Scientists discover closest known Earth-sized world only 22 light-years away

A group of astronomers detected a giant planet revolving around a small cool star. The rare discovery is about 35 light-years away from Earth.&nbsp;

According to the reports, the giant planet looked like Saturn and was detected by a 'wobble' in star's motion.&nbsp;

The 'wobble' is caused due to the gravitational pull of the planet.

In a rare event, astronomers discover Saturn-like planet orbiting small cool star

An astronomer has discovered the closest black hole to the Earth, about 1,000 light-years away.&nbsp;

The hole is so close that two stars swirling around an invisible object is visible with the naked eye on a clear dark night in the southern hemisphere.

The previous black hole was three times away from the current discovery. According to astronomers, it was at a distance of 3,200 light-years.

Every light year is 5.9 trillion miles.

The recently discovered black hole is the nearest to the earth, according to astronomers.

According to media reports, on the scale of the Milky Way, the black hole is in the backyard. Close to the doorstep.

The black hole which is centrally located in the Milky Way is more than 25,000 light-years away.

Scientists can discover these holes, like the latest one, when they absorb parts of a partner star or any other objects falling into them.

And most of them remain unspotted as they do not have anything close to swallowing.

An inner star’s orbit helped in the discovery of the closest black hole.

The 25-miles diameter hole was a part of the three-star dance system called HR 6819.

And the two stars were not very close to be sucked.

European scientists in Chile found something four to five times the mass of the sun was pulling on the inner star and said it was a black hole.

The spotting of the black hole suggests that there could be more out there.

There are around one billion small dense objects in the Milky Way, according to astronomers.

The new planet is in constellation Lyra and is likely to be rocky and possibly could have oceans, scientists said.

A planet which about 1,200 light-years away from Earth and 40 per cent larger than its size may be habitable, according to US researchers.

Kepler-62f, which is in the direction of the constellation Lyra, is within the range of planets that are likely to be rocky and possibly could have oceans, scientists said. 
 
NASA&#39;s Kepler mission discovered the planetary system that includes Kepler-62f in 2013, and it identified Kepler-62f as the outermost of five planets orbiting a star that is smaller and cooler than the sun, they said.

But the mission did not produce information about Kepler-62f&#39;s composition or atmosphere or the shape of its orbit.

Now, scientists from University of California Los Angeles (UCLA) and University of Washington came up with possible scenarios about what its atmosphere might be like and what the shape of its orbit might be to determine whether the planet could sustain life.

&quot;We found there are multiple atmospheric compositions that allow it to be warm enough to have surface liquid water.

This makes it a strong candidate for a habitable planet,&quot; said Aomawa Shields from UCLA.

On Earth, carbon dioxide makes up 0.04 percent of the atmosphere, researchers said.

Because Kepler-62f is much farther away from its star than Earth is from the sun, it would need to have dramatically more carbon dioxide to be warm enough to maintain liquid water on its surface, and to keep from freezing, they said.

Researchers ran computer simulations based on Kepler-62f having an atmosphere that ranges in thickness from the same as Earth&#39;s all the way up to 12 times thicker than our planet&#39;s.

Kepler-62f also has various concentrations of carbon dioxide in its atmosphere, ranging from the same amount as is in the Earth&#39;s atmosphere up to 2,500 times that level, and there are several different possible configurations for its orbital path, scientists said.

They found many scenarios that allow it to be habitable, assuming different amounts of carbon dioxide in its atmosphere.

Shields said that for the planet to be consistently habitable throughout its entire year, it would require an atmosphere that is three to five times thicker than Earth s and composed entirely of carbon dioxide.

Having such a high concentration of carbon dioxide would be possible for the planet because, given how far it is from its star, the gas could build up in the planet&#39;s atmosphere as temperatures get colder to keep the planet warm, she said.

Scientists made their calculations of the shape of the planet&#39;s possible orbital path using an existing computer model called HNBody, and they used existing global climate models to simulate its climate.

The findings were published in the journal Astrobiology.
