TESS catches a comet: the new satellite of search of exoplanets of the NASA sees a space of rock in orbit

TESS discovered a comet that rose some 29 million miles (48 million kilometers) from Earth on July 25, just hours before its first official science operations.

NASA's TESS spacecraft has finally begun its mission to find planets outside of our solar system.

But in its first images, it is not about exoplanets captured by the satellite.

Comet 2018 N1 is found in the Piscis Austrinus constellation, and can be seen as a bright white circle passing through the frame from left to right.

The Transiting Exoplanet Survey Satellite (TESS) satellite started scientific operations on July 25 after a series of images to assess its ability to observe a large region of the sky for a long time.

The sequence revealed by Comet / 2018 N1, which was first detected by NASA's Near-Earth Infrared Object Survey Explorer (NEOWISE) on June 29, was captured over the course of 17 hours.

According to NASA, TESS took the images in the final hours of its start-up phase.

Comet 2018 N1 is found in the Piscis Austrinus constellation, and can be seen as a bright white circle passing through the frame from left to right.

"The tail of the comet, which consists of gases transported from the comet by a flow of the sun called the solar wind, extends to the top of the frame and rotates gradually as the comet slides through the field of vision," explains POT.

TESS also saw stars and what NASA says is light lost from Mars, when the red planet was closer to Earth.

The ship underwent weeks of testing before the official start of its mission, after its launch last April.

It is expected that your first observations will arrive early this month, with transmissions sent to Earth every 13.5 days thereafter.

"I am delighted that our new planet hunter mission is ready to begin touring the neighborhood of our solar system in search of new worlds," said Paul Hertz, director of NASA's astrophysics division at Washington headquarters. .

"Now that we know there are more planets than stars in our universe, I look forward to the strange and fantastic worlds we are forced to discover."

In May, TESS released its first test image of the orbit, exactly one month after launching its mission to find unknown exoplanets.

The satellite in transit of NASA's Exoplanet Satellite (TESS) completed a lunar flyby on May 17, passing approximately 5,000 miles from the moon en route to its final work orbit.

The Transiting Exoplanet Survey Satellite (TESS) satellite started scientific operations on July 25 with a series of images to test its ability to observe a wide region of the sky for a long time.

WHAT IS SPACECRAFT TESS?

The new & # 39; planetary hunter & # 39; NASA, which will be Kepler's successor, is equipped with four cameras that will allow you to see 85 percent of the entire sky, while looking for exoplanets that orbit stars less than 300 light-years away.

By studying objects much brighter than Kepler's objectives, TESS is expected to discover new clues about the possibility of life elsewhere in the universe.

Its four wide-field cameras will see the sky in 26 segments, each of which will observe one by one.

In its first year of operation, it will map the 13 sectors that make up the southern sky.

Then, the following year, it will tour the northern sectors.

"We learned from Kepler that there are more planets than stars in our sky, and now TESS will open our eyes to the variety of planets around some of the closest stars," said Paul Hertz, director of the Division of Astrophysics at the headquarters of The NASA.

"TESS will launch a wider network than ever for enigmatic worlds whose properties can be tested by NASA's upcoming James Webb Space Telescope and other missions."

Tess is 5 feet (1.5 meters) wide and shorter than most adults.

The observatory measures 4 feet wide (1.2 meters), not counting the solar wings, which fold for launch, and weigh only 800 pounds (362 kilograms).

NASA says it's somewhere between the size of a refrigerator and a stacked washer and dryer.

Tess will point to a single elongated orbit that passes within 45,000 miles of Earth at one end and as far as the moon's orbit at the other end.

It will take Tess two weeks to go around the Earth.

This gave him a gravitational assist & # 39; to maneuver towards its final destination.

His initial test photo, captured in a two-second exposure with one of his four cameras, revealed more than 200,000 stars in the Centaurus constellation, with a glimpse of the Coalsack Nebula and the bright star Beta Centauri.

The $ 337 million satellite launched on April 18 on a Falcon 9 rocket on its way to what scientists have praised for a "mission for the ages."

TESS is equipped with four cameras that will allow you to see 85 percent of the entire sky, as it searches for exoplanets orbiting stars less than 300 light-years away.

It has not yet reached its final orbit, but is expected to arrive in the coming weeks, thanks in part to a small boost from the moon's gravity on May 17.

"One of the most important questions in the exploration of exoplanets is: if an astronomer finds a planet in the habitable zone of a star, will it be interesting from a biologist's point of view?" Said George Ricker, principal investigator of TESS. at the Kavli Institute for Astrophysics and Research Space.

"We hope that TESS will discover a series of planets whose atmospheric compositions, which have possible clues about the presence of life, could be accurately measured by future observers."
