Universe: A Jupiter-sized “cannonball” has been spotted in space

An amazing exoplanet

The newly discovered exoplanet is about the size of Jupiter but nine times more massive than the gas giant. This is not the only thing that separates the two planets.

AHMEDABAD – A research team from India has discovered an amazing exoplanet: orbiting a star 730 light-years from Earth, the planet called TOI-4603b is about the size of Jupiter in our solar system. But there are several things that distinguish the newly discovered exoplanet from the gas giant orbiting our sun.

First, there’s its density: the exoplanet TOI-4603b has a density nearly nine times that of Jupiter. While the gas giant in our solar system has a density of 1.33 grams per cubic centimeter, TOI-4603b has a density of 14.1 grams per cubic centimeter. For comparison: the density of the Earth is 5.51 grams per cubic centimeter, the density of lead is 11.3 grams per cubic centimeter, and the density of iron is 7.9 grams per cubic centimeter. So it looks as if researchers have detected a particularly dense “cannonball” in space.

The newly discovered exoplanet orbits its star in 7.25 days

The second way in which the newly discovered exoplanet TOI-4603b is significantly different from Jupiter of roughly the same size is in its orbit around its host star. Jupiter takes 11 years, 315 days, and 3 hours to revolve around the sun – exoplanet TOI-4603b only needs 7.25 days.



Look deep into the universe – this is how Hubble sees the universe

The Bubble Nebula (NGC 7635) in the constellation Cassiopeia is an emission nebula about 7,100 light-years from Earth. The bubble shape is formed by the stellar wind from a star spewing out large amounts of gas. The gases collide with a huge molecular cloud located in this region – a shock wave is generated that forms the outer envelope of the gas bubble.

This Hubble Space Telescope image shows the open star cluster Trumpler 14 (also known as Collinder 230) in the keel of the constellation Ship. The star cluster is about 9,000 light-years away in the Carina Nebula. It is one of the younger star clusters in the Milky Way, only 300,000 to 500,000 years old. Trumpler 14 is home to about 2,000 young stars, including one of the brightest stars in the Milky Way.

The Pillars of Creation is one of the most famous Hubble images. Here, a NASA space telescope is looking at a small region of the Eagle Nebula (M16), a star-forming region 6,500 light-years from Earth.

Spiral galaxy M83 (the Southern Pinwheel Galaxy) is a popular target for amateur astronomers. Located 15 million light-years away in the constellation of Aquarius, it is one of the brightest spiral galaxies in the southern hemisphere sky. Thousands of star clusters, hundreds of thousands of individual stars, and the remnants of dying stars (supernovae) can be seen in the Hubble image.

The Ring Nebula (M57) is a planetary nebula in the constellation Lyra. It’s the glowing remains of a once sun-like star that released its outer layer of gas some 20,000 years ago. The ring is about 1.3 light-years across. Inside a white dwarf star.

The iconic Horsehead Nebula is a popular target for amateur and professional astronomers alike. The Horsehead Nebula is part of a dark cloud in the constellation of Orion, illuminated by a bright red nebula (IC 434). The nebula is about 1,500 light-years away from Earth.

This image of the elliptical radio galaxy Hercules A is also from NASA’s Hubble Space Telescope. The galaxy is 2.1 billion light-years away in the constellation Hercules. Huge jets of plasma, thought to be powered by a supermassive black hole, can be seen in the galaxy’s interior.

This image shows two spiral galaxies interacting with each other. The group is called Arp 273. According to NASA, the unusual spiral patterns indicate that the two galaxies in this group are interacting, or interacting with each other. Arp 273 is about 300 million light-years from Earth, and the two galaxies are actually tens of thousands of light-years apart. Only a very subtle “bridge” connects the two.

A gorgeous spiral galaxy is visible in this image from NASA’s Hubble Space Telescope. It is spiral galaxy NGC 2841, located 46 million light-years away in the constellation Ursa Major.

This Hubble shot is like fireworks. In fact, it is the star-forming region NGC 3603 in the “Keel of the Ship” constellation. About 20,000 light-years away, the nebula isn’t as peaceful as it appears: ultraviolet light and violent stellar winds have exposed the star cluster. NGC 3603 hosts some of the largest stars known. They die early because they quickly burn hydrogen, which leads to a supernova explosion.

It was an exoplanet NASA’s TESS Space Telescope It was discovered, which was sent into space specifically to search for exoplanets. TESS watches the stars, looking for brief dips in brightness that occur when a planet passes in front of the star. With this so-called transit method Countless exoplanets have already been discovered. The Indian research team took data from TESS and attempted to confirm the planet’s existence using the radial velocity method.

One of the largest and densest of the giant planets

It measures how the gravity of an exoplanet affects a star. If you know the mass of a star, you can determine the mass of an exoplanet. The research team wrote in the study: “It is one of the largest passing giant planets known so far in its magnitude and density.” on a prepress server ArXiv can access It is for publication in the specialized journal Astronomy and Astrophysics Letters It was accepted.

The exoplanet also has an elliptical and eccentric orbit, which indicates that it may anchor itself in its orbit. TOI-4603b is accompanied by an orbiting brown dwarf at a distance of 1.8 AU and may have interacted with it in the past. (unpaid bill)
