Invisible rogue planets without stars? NASA’s new space telescope could find hundreds of them


The Nancy Grace Roman Space Telescope, NASA’s upcoming observatory expected to launch in the mid – 1920s, could reveal a multitude of vicious planets that do not orbit stars in our Milky Way galaxy. , according to new research.

These exoplanets, or planets that lie outside our solar system, move through the galaxy on their own and are not trapped in orbits around stars that cause the Earth to revolve around the sun. Understanding these supposed planets could shed more light on the formation, evolution, and disruption of planetary systems.

These vicious planets are difficult to detect and scientists have found only a few. But the capabilities of the Roman Space Telescope will allow it to find and characterize these roaming nomadic planets.

“While our view of the universe has expanded, we have realized that our solar system can be unusual,” said Samson Johnson, a study writer and graduate student at Ohio State University, in a statement. “Novel will help us learn more about how we fit into the cosmic scheme of things by studying evil planets. Imagine that our small rocky planet just floats freely in space – that’s what this mission will do to us. help find. “

The telescope, named in honor of the agency’s first chief, is equipped with a powerful 2.4-meter mirror that will allow it to search for exoplanets. The telescope will stare at large swaths of the sky and look at gravitational microlensing events, where a planet and the star orbiting it pass in front of a background star.

Microlensing occurs when the presence of something massive can actually last space-time, such as black holes, but it can also occur around planets.

For example, if a rough planet is in agreement with a distant star, the light from that star will essentially bend around the planet, leading to a greater effect. Scientists can use the changes in light around the planet to measure the mass of the planet.

“The microlensing signal of a rough planet lasts only a few hours and a few days and is then gone forever,” said Matthew Penny, a study co-founder and assistant professor of physics and astronomy at Louisiana State University in Baton Rouge, in a statement. “This makes them difficult to observe from Earth, even with multiple telescopes. Novel is a game-changer for sucking planet searches.”

Given the fact that evil planets do not emit light like stars, or even enough heat to see in infrared light, these otherwise invisible worlds will become visible through the Roman Telescope’s observations of micro-events.

Understanding of rogue planets

The telescope’s field of view is a hundred times larger than Hubble’s infrared instrument, which means the telescope can observe more in less time, the agency said. It will also create imaging with high contrasts of individual nearby exoplanets.

The Roman Space Telescope will measure the light of a billion galaxies and attempt to provide data that could answer important questions about how common planetary arrangements are for our own solar system, as well as how many planets can hire life.

It also has the ability to find vicious planets as small as Mars, which is slightly larger than half the Earth.

So how do rogue planets form?

Planet birth itself is a violent, unjust process. Gas and dust in discs around young stars clump together and gradually grow in size to form planets. But collisions between objects on larger scales, or even too close to another planet come into orbit around the star, as the star itself, can kick the planet out of its system.

And then the planet is on its own – he has become rogue.

It is also possible that solitary planets may form on their own in isolated clouds of gas and dust.

The Roman Telescope will help researchers determine how these planets form by providing information about how many there are as their masses – which may help to indicate their origin story.

Recent research with estimates of ground-based telescopes suggests that the Roman Telescope could find hundreds of vicious planets, scientists help to understand how often they are in the Milky Way. The telescope’s discoveries may reveal that there are actually more rogue planets than there are stars in our galaxy, according to the study.

The Roman telescope will be 10 times more sensitive to the detection of bad planets than other telescopes and it will search for them over 24,000 light-years between our sun and the center of the galaxy.

“The universe could be rocking with rough planets and we would not even know it,” Scott Gaudi, a study co-op and a professor of astronomy at Ohio State University, said in a statement. “We would never discover it without conducting an in-depth, space-based microlensing study like Roman will do.”
