NASA made a mad discovery of a rare system of six hyperactive exoplanets, with a seventh “misbehaving” infant star. This system of planets with a star is quite similar to our solar system, which raises curiosity to explore more of this region, said scientists.&nbsp;

This system of exoplanets is orbiting a relatively close dwarf star in the Milky Way called TOI-1136, which is 270 light years away from Earth. There are a huge number of such exoplanet systems in this region that inspired scientists to study deeper.

"Because few star systems have as many planets as this one does, it's getting close in size to our solar system," Tara Fetherolf, team member and a visiting professor of astrophysics at the University of California, said in a statement. "It's both similar enough and different enough that we can learn a lot."

<h2>Discovery of young exoplanet system with infant star could help in understanding solar system better</h2>

The initial study of the TOI-1136 planetary system was done by NASA using its Transitioning Survey Satellite (TESS) in 2019. Fetherolf and team found masses of planets in the region with their orbits and even some trace of their atmospheres.&nbsp;

The planets in the system were designated names between TOI-1136 b to TOI-1136 g, and termed as "sub-Neptune" planets. The smallest of the six confirmed planets has a width twice that of Earth, while some of its sibling planets are as large as four times the size of our planet.&nbsp;

Later it was found that TOI-1136 exoplanets are so close to their parent star that they only take 88 Earth days to complete one orbit. This was a major discovery because 88 days is the orbital period of Mercury, which is the closest planet to the Sun, meaning that all these planets may be closer to their star than that tiny planet is to the Sun.&nbsp;

"They're weird planets to us because we don't have anything exactly like them in our solar system," Rae Holcomb, team member and a physics Ph.D. candidate at the University of California, said in a separate statement. "But the more we study other planet systems, it seems like they may be the most common type of planet in the galaxy."

This system of TOI-1136 is quite young, much younger than our solar system, which makes TOI-1136 a toddler in comparison to our home system. This could be of immense importance for astronomers and scientists to learn more about the formation of the solar system, which is a hot topic, said Fetherolf.&nbsp;

"Any time we find a multi-planet system it gives us more information to inform our theories about how systems come to be and how our system got here."

The hyperactivity of these much younger exoplanets and a star will be a problem for scientists as it will make high-precision measurements difficult, as they are still juvenile stars.&nbsp;

NASA spots a system of six 'sub-Neptunes' with hyperactive 'toddler' star

NASA&nbsp;announced two new missions to Venus on Wednesday that will launch at the end of the decade and are aimed at learning how Earth's nearest planetary neighbor became a hellscape while our own thrived.

"These two sister missions both aim to understand how Venus became an inferno-like world, capable of melting lead at the surface," said Bill Nelson, the agency's newly-confirmed administrator.

"They will offer the entire science community the chance to investigate a planet we haven't been to in more than 30 years."

The missions have been awarded about $500 million under&nbsp;NASA's Discovery Program, and each is expected to launch in the 2028-2030 timeframe.

Both missions were picked from a competitive, peer-reviewed process based on their scientific value and feasibility of their plans.

DAVINCI+, which stands for Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging, will gather more detail on the composition of Venus' primarily carbon dioxide atmosphere, to learn how it formed and evolved.

The mission also seeks to determine whether the planet once had an ocean.

A descent sphere will plunge through the dense atmosphere which is laced with sulfuric acid clouds.&nbsp;

It will precisely measure the levels of noble gases and other elements to learn what gave rise to the runaway greenhouse effect we see today.

DAVINCI+ will also beam back the first high resolution images of the planet's "tesserae," geological features roughly comparable with Earth's continents whose existence suggests Venus has plate tectonics.

The results could reshape scientists' understanding of terrestrial planet formation.

The other mission is called VERITAS, an acronym for Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy.

This will aim to map the Venusian surface from orbit and delve into the planet's geologic history.

Using a form of radar that is used to create three-dimensional constructions, it will chart surface elevations and confirm whether volcanoes and earthquakes are still happening on the planet.

It will also use infrared scanning to determine rock type, which is largely unknown, and whether active volcanoes are releasing water vapor into the atmosphere.

While the mission is&nbsp;NASA&nbsp;led, the German Aerospace Center will provide the infrared mapper, while the Italian&nbsp;Space&nbsp;Agency and France's Centre National d'Etudes Spatiales will contribute to the radar and other parts of the mission.

"It is astounding how little we know about Venus, but the combined results of these missions will tell us about the planet from the clouds in its sky through the volcanoes on its surface all the way down to its very core," said Tom Wagner,&nbsp;NASA's Discovery Program scientist.&nbsp;

"It will be as if we have rediscovered the planet."

NASA's last Venus orbiter was Magellan, which arrived in 1990, but other vessels have made fly-bys since then.
