The ESA/NASA Solar Orbiter spacecraft recently captured a giant solar eruption on 15 February 2022 that extended millions of kilometres into space. This is the largest solar prominence eruption ever observed in a single image together with the full solar disc. Read more© Solar Orbiter/EUI Team/ESA & NASA

Scientists have found largest galaxy ever. It is 16.3 Million Light Years long! The galaxy, named Alcyoneus is discovered about 3 billion light-years away from Earth. Alcyoneus is radio galaxy, means is has a supermassive black hole at its center. This galaxy is four times bigger than previous title holder, IC 1101.

What are the two orange lobes in the first image?

Those lobes are the pair of plasma plumes ejected from Alcyoneus' black hole. It is the largest structure made by a galaxy known thus far. Read moreImage Credit: Martijn Oei et al.

✨ Asteroid Elektra has a third satellite! This discovery makes Electra the first ever quadruple asteroid system!Elektra was first discovered in 1873, orbiting in the asteroid belt between Mars and Jupiter. Oblong-shaped and 260 km across on its longest side, it is a relatively large asteroid and completes an orbit of the sun every five years. In 2003, the first moon was discovered orbiting Elektra, and in 2014 a second — their orbits are shown in orange and green. The discoveries were interesting, but not unusual — more than 150 asteroids are known to have one or two moons, in the same way planets can have moons. But now a team of astronomers led by Anthony Birdo of Thailand's National Institute of Astronomical Research has found third moon around the asteroid, whose orbit is marked in blue.

? New exoplanet - Proxima dA third planet has been detected orbiting the closest star to our solar system, Proxima Centauri. It is estimated to be just 25% as massive as Earth, or around twice the mass of Mars, the planet – known as Proxima d – is one of the lightest exoplanets ever found. Using the Very Large Telescope in Chile, the team looked at how the star wobbled under the gravitational pull from orbiting planets. This is what is known as the radial velocity method. From the star’s wobbles, the team deduced the highly likely presence of a third planet in the system. Orbiting its host star at 0.029 times the distance between Earth and the sun, Proxima d sits within Proxima Centauri’s habitable zone, the region around the star in which water can remain liquid.

? An image of Jupiter's rings taken by the Galileo spacecraft in 1996Jupiter's rings are much darker than Saturn's, and unlike the famous rings of Saturn, Jupiter's rings are made of dust, not ice. Jupiter's rings were discovered in 1979 by the passing Voyager 1 spacecraft.
