A unique exoplanet nearly nine times the mass of Earth was discovered after it unexpectedly ‘blows’ its star 48 light-years away.
Earth was discovered in the constellation Lupus. also known as the wolf And of course it must be It’s a “golden target for future studies” because there are no ‘equivalents,’ say scientists.
It is the first time an exoplanet with an orbit of more than 100 days has passed a star bright enough to be seen by the naked eye.

WHAT DO WE KNOW ABOUT PLANET ‘D’ IN THE NU2 LUPI SYSTEM?
The newly discovered planet ‘d’ is one of three exoplanets orbiting a sun-like star called Nu2 Lupi.
Nu2 Lupi is approximately 48 light-years from Earth and is one of only three stars visible to the naked eye. which are known to host many transiting planets.
Planets ‘b’, ‘c’ and ‘d’ have masses between the masses of Earth and Neptune with orbits of 11.6, 27.6 and 107.6 days respectively.
Planet d’s orbit would put it between Mercury and Venus in our solar system.
it is not habitable But there is much more water than Earth, 25% of its mass is made up of water. compared to less than 0.1 percent in our world.
However, it is not liquid water. Instead, it is in the form of high-pressure ice or high-temperature steam.
Planet d has a mass 8.8 times that of Earth and is ‘sure to be a gold target for future studies’ because it has no ‘equivalent’, the scientists said.
The ‘extremely exciting’ discovery happened by chance as researchers were exploring two other planets in a nearby bright stellar system.
All three orbit a sun-like star called Nu2 Lupi, one of the only naked-eye stars known to have multiple transiting planets.
The newly discovered planets ‘b’, ‘c’ and ‘d’ have masses between the masses of Earth and Neptune with orbits lasting 11.6, 27.6 and 107.6 days, respectively.
The European Space Agency (ESA) has said that no one is inhabitable. But planet ‘d’ will be a very attractive target for both the Hubble Space Telescope and the James Webb Space Telescope when it launches later this year.
‘In combination with the bright progenitor star long orbital period and suitability for tracking preferences It excites the planet very much – it is a special object that has no equivalent. And it is sure to be a golden target for future studies,’ said study co-author David Ehrenreich from the University of Geneva in Switzerland.
Planet d’s orbit puts it between Mercury and Venus in our solar system, while b and c will lie within Mercury’s orbit, which takes 88 days to orbit the sun.
Researchers say that planet b is mostly rocky, but c and d contain much more water than Earth. One quarter of the mass of each planet is made up of water. compared to less than 0.1 percent of the world
However, this water is not a liquid. Instead, it is in the form of high-pressure ice or high-temperature steam.
The discovery of planet d, found to have a mass of 8.8 Earth times, is one of the first results from ESA’s Cheops (CHaracterising ExOPlanet Satellite).
Scientists say ‘Exciting’: Earth has been discovered in the constellation Lupus, also known as Wolves, and ‘sure to be a gold target for future studies’ because there is no ‘equivalent’, scientists say.
CHEOPS: The Quest to Create a Character Known in EXOPLANETS
Cheops is the acronym for the ESA-defined ExOPlanet Satellite mission.
It was the first mission dedicated to studying nearby bright stars. which is known to be an exoplanet
It will accurately observe the size of the planet as it passes in front of its parent star.
It focuses on planets in the super-Earth to Neptune size range. With the data that allows to obtain the density of a large number of planets.
Cheops is the first small or S-class mission in the ESA’s science program.
It is a collaboration between ESA and Switzerland, with a dedicated consortium led by the University of Bern and with significant contributions from 10 other ESA member states.
The first planet Cheops studied was WASP-189b, a super-hot Jupiter that orbits its star every three days.
Cheops project scientist Kate Isaak said that while none of the planets are habitable, it’s still not a habit. But their diversity makes the system even more exciting. And it’s a great future opportunity to test how these objects form and change over time.
‘There is also the potential to find rings or moons in the Nu2 Lupi system, as Cheops’ excellent accuracy and stability allows it to detect objects similar in size to Mars.’
So far, most of the long-lived exoplanets have been discovered around stars that are too dim for detailed monitoring. This means that little is known about the properties of their planets.
Nu2 Lupi, however, is bright enough to be seen by powerful telescopes in space and large ground-based observatories.
transit of planets When a celestial body moves forward a larger object in space. This gives researchers the opportunity to study the planet’s atmosphere, orbit, size and interior.
The transiting planet blocks a small but detectable portion of the star’s light as it passes in front of the star. And it was this incident light that led the Cheops researchers to discover.
It is extremely rare to see long-lived exoplanets in transit. because they orbit very far from their stars.
Lead author Laetitia Delrez from the University of Liège in Belgium said: “Transition systems such as Nu2 Lupi are critical in understanding how planets form and evolve. Because we can compare multiple planets around the same bright star in great detail.”
‘We intended to build on a previous study of Nu2 Lupi and observe planets b and c crossing faces of Nu2 Lupi and Cheops, but during the transit of planet c we found something amazing: an unexpected transit by Planet ‘d’ which is later in the system.
‘With its overall properties and orbit This makes the planet a good target for studying exoplanets with low atmospheres around sun-like stars.’
The aim of Cheops, an ESA mission developed in collaboration with Switzerland. is to help better understand known exoplanets and discover new ones.
The findings are published in the journal Nature Astronomy.
An important discovery in humanity’s search for alien life.
Discovery of the pulsar
British astronomer Dame Jocelyn Bell Burnell was the first person to discover pulsars in 1967 when she saw a radio pulsar.
since then Other types of pulsars that emit X-rays and gamma rays have also been found.
Pulsars are neutron stars with high rotating magnetic fields. But when it was first discovered It is believed that they may have come from aliens.
‘Wow!’ Radio signal.
In 1977, astronomers were looking for extraterrestrial beings in the night sky over Ohio. A radio signal was found so powerful that he wrote, ‘Wow! next to his information
In 1977, astronomers were looking for extraterrestrial life in the night sky over Ohio. A radio signal was found so powerful that he excitedly wrote ‘Wow!’ next to his information
The 72-second explosion detected by Dr Jerry Ehman through a radio telescope. from Sagittarius but does not correspond to known celestial objects.
Conspiracy theorists since then have claimed, ‘Wow! Signal’, which is 30 times stronger than background radiation, is a message from an intelligent alien.
Fossilized Martian microbes
In 1996, NASA and the White House announced a bomb that the rock contained traces of insects on Mars.
The meteorite, identified as Allen Hills (ALH) 84001, crashed into Antarctica’s frozen waste 13,000 years ago and was recovered in 1984.
A photograph was revealed showing a remarkably long and realistic-looking segmented object.
A photograph is revealed, showing a remarkably real-looking long segmented object (pictured).
However, the excitement did not last long. other scientists Ask if the meteorite sample is contaminated.
They also argue that the heat generated when rocks are blasted into space might create mineral structures that could be mistaken for microfossils.
Tabby’s Star Behavior in 2005
The star, known as KIC 8462852, is 1,400 light-years away and has baffled astronomers since it was discovered in 2015.
It dims much faster than other stars. which some experts suggest is a signal of aliens controlling the star’s energy.
The star, known as KIC 8462852, is 1,400 light-years away and has surprised astronomers since it was discovered in 2015 (artist impression).
Recent studies have ‘eliminated the possibility of extraterrestrial superstructures’ and instead suggest that a ring of dust may produce strange signals.
Exoplanets in the Goldilocks zone in 2017
In February 2017, astronomers announced that they had found a stellar system with planets that could support life in just 39 light years.
Seven Earth-like planets have been discovered orbiting the dwarf star ‘Trappist-1’, and all of them may have water at the surface. which is one of the essential elements of life
Three planets are in such good condition. Scientists say life may have evolved.
Researchers claim they will know if life exists on any planet within a decade and say: ‘This is just the beginning’.
