Telescope discovers another Earth-sized habitable planet

Using the Transiting Exoplanet Survey Satellite (TESS), NASA has discovered a habitable planet the size of Earth orbiting a star.

The habitable planet orbits a star in the range of distances at which conditions may allow the presence of liquid water on its surface.

According to a statement from NASA, scientists confirmed the discovery, called the TOI 700 d, using NASA’s Spitzer Space Telescope. NASA also said the TOI 700 d is one of the few Earth-sized planets discovered in a star’s habitable zone so far.

She added:

Others include various planets in the TRAPPIST-1 system and other worlds discovered by NASA’s Kepler Space Telescope.

TOI 700 is a small, fresh M dwarf star located just over 100 light years away in the southern constellation of Dorado. It is about 40% of the mass and size of the sun and about half the surface temperature. The star appears in 11 of the 13 sectors observed by TESS during the first year of the mission, and scientists captured several transits from its three planets.

The star was originally misclassified in the TESS database as being more similar to our Sun, which meant that the planets looked bigger and hotter than they really are. Several researchers, including Alton Spencer, a high school student who works with TESS team members, have identified the error.

Emily Gilbert, a graduate student at the University of Chicago, said:

When we corrected the parameters of the star, the sizes of its planets dropped and we realized that the outermost was the size of the earth and the habitable zone.

Additionally, in 11 months of data, we saw no star bursts, which increases the chances of the TOI 700 d being habitable and facilitates modeling of its atmospheric and surface conditions.

It is worth mentioning here that the TESS satellite monitors sectors of the sky for 27 days at a time, allowing the satellite to track changes in the brightness of a star caused by an orbiting planet crossing in front of it.

NASA published pictures of two giant asteroids

NASA published an amazing image of two giant asteroids traveling in the asteroid belt, both of which are larger than some of the cities in the world.

The American Space Agency shared a snapshot that tracks the movement of the large asteroids Lina and Klotho, located in the asteroid belt between Mars and Jupiter. The Lina is about 37 miles (60 km) in diameter and has more than 2,000 days in orbit around the Sun. Klotho is slightly larger, having 50.9 miles (82 km) in diameter and has a 1596-day orbit around our main star.

NASA observed space rocks using the NEOWISE telescope. He also states on his official website:

“appearing as rows of orange dots, the brightest sets of dots belong to the asteroids of Klotho and Lina. Both rotate in the main asteroid belt between Mars and Jupiter, while smaller and more distant asteroids can also be seen on this image ”

These space objects were photographed by NEOWISE as part of the Wise mission (Wide-field Infrared Survey Explorer) asteroid hunting project. 

Cosmic stones within the asteroid belt supposedly pose almost no danger to the Earth, due to the role that Jupiter plays in the solar system. The giant planet has such a powerful gravitational attraction that it actually helps to keep the asteroid belt in place, so objects do not travel throughout the system.

If Jupiter did not use its gravitational pull on these objects in the belt, the inner planets would be constantly at risk of collisions with large asteroids.

“The presence of Jupiter actually protects Mercury, Venus, Earth, and Mars from repeated collisions with asteroids!”, The NASA statement said.

The probability of a major asteroid colliding with the Earth is one in 300,000 chance. However, such a prospect is possible, NASA says.

A “Meteorite” falls in Nigeria destroying more than 100 houses and leaving a huge crater

On the morning of Saturday 28 March 2020, a large meteorite crashed in Akure (Nigeria), destroying more than 100 houses and leaving a 21-meter crater on the ground. Experts from the Awbaowo University of Obafemi (Nigeria) denied the local police who initially claimed that a bomb explosion had created the 21-meter crater.

According to Nigerian sources, the explosion destroyed the Akure-OVO road and seriously damaged dozens of houses, from 50 to 100, as well as schools and churches.

It is interesting that initially the authorities denied the meteorite’s fall and claimed that the cause for the explosion was a truck with explosives, which was transported to a neighboring state. Ondo State Governor Rotimi Akeredolu said the blast was an accident.

Then the version changed and the truck was no longer just transporting explosives, but it was supposedly a terrorist act.

Now, a team of experts and scientists came to the conclusion that everything that happened was a fall of a large meteorite.

The blast that shook Akure, the state capital of Ondo, on Saturday, was caused by a giant cosmic rock, a team of experts concluded.

Led by Adepelumi Adekunle, a professor of geophysics and seismic engineering at Obafemi Avolovo University, the team said that the meteorite entered the atmosphere of our planet at a “43 degree angle”.

Adepelumi Adekunle’s report reads:

“My research team conducted a detailed analysis of the impact site. A round impact crater was discovered with a diameter of 21 m and a depth of 7.8 m, which indicates a natural phenomenon.

– It was found that water is oozing from the edges of the crater. Preliminary field studies of vibration, noise, seismicity, analysis of water, radioactivity, rocks and soil were carried out.

“Our findings suggest that the impact of the explosion covers a radius of 1 km from the vicinity of the crater.” No signs of fire or burning were found in the vicinity. “

“No signs of radioactive radiation were found within the crater and in the immediate vicinity of it. Field data indicate that a meteorite from the asteroid belt was moving at high speed from space, and fell at an angle of 43 degrees in the southwestern part of the country “

A local source said that after the incident, no one was missing and no one was killed. The most interesting thing in the report is the mention that “unusual stones and strange metal objects” were found inside the crater. So what actually fell in Nigeria – a meteorite or a UFO?

Something strange is happening with the interstellar comet 2I / Borisov

When astronomers see something in the Universe that at first glance seems to be one of a kind, this will certainly cause great excitement and attention.

This mysterious guest from the depths of space first attracted the attention of celestial observers at the end of August 2019, when it was officially discovered sweeping through the solar system along a trajectory indicating interstellar origin.

After analyzing the object, astronomers identified it as a comet called Comet 21 / Borisov, which is the first identified comet and the second observable interstellar alien after the infamous Oumuamua, who arrived here from another star.

NASA claims that they do not know where and when the comet began to move towards our Sun. Gravity of the Sun slightly deflects its trajectory, but cannot capture it due to the shape of the orbit and its high speed of about 160,934 km / h.

Hubble showed that the comet’s heart, a loose accumulation of ice and dust particles, was probably no more than 975 meters across, about the length of nine football fields.

Now, this month, astronomers have discovered that something strange is happening by checking the object.

In the next video, nemesis maturity explains what happens to this mysterious interstellar guest.
