Astronomers confirmed that in early January 2022 scientists observed star Just before it turned into a “supernova”, and Comet Leonard continued to shine and directed the government to “NASA” to extend the work of the International Space Station until the end of the current decade, this is one of the most important events of the past week.

James Webb publishes his mirror

did NASA agency By successfully directing its latest space telescope to open the wings of its massive mirror, the James Webb Telescope’s 6.5-meter-wide, gold-covered mirror has been fully deployed.

Leonard continued to shine

Comet Leonard shone beautifully in Earth’s night sky in the weeks and days around mid-December 2021, as the comet moved away from our planet and continued to approach the Sun, fading naturally from view, but observers note that the icy visitor recently launched several explosions, and its tail has taken a twisted appearance.

monitor A star before it explodes

Astronomers have discovered the explosion of a star ten times the mass of the Sun, a red giant star, once it transforms into a supernova, and this data could expand what is known about what massive stars do in the moments before they die. The star was located at a distance of about 120 million light-years from Earth in the galaxy NGC 5731.

Earth in the gutter

Earth rotates around the sun In an elliptical orbit, which means there are two distinct moments in its year-long journey when the planet is either farthest from the sun (aphelion) or closest to the star (perihelion). Tuesday (January 4) saw perihelion, when it was The Earth is closer to the Sun by about 5 million km than it will be at apogee in early July.

Meteor explodes over Pittsburgh early this year

NASA’s Meteor Observation Network detected a large meteor explosion over Pittsburgh, Pennsylvania on Jan. 1 and released an energy blast equivalent to 30 tons of the explosive TNT. People in the city heard what sounded like a “bang.” It is believed that the meteorite was about 3 feet wide and was moving at a speed of about 72,420 kilometers per hour.

Junk falls in the Pacific Ocean

Register on Wednesday (January 5th), missile crash Weighing 3.5 tons in an uncontrolled manner east of French Polynesia in the Pacific Ocean. This object was the upper stage of a Russian Angara A5 rocket, which was launched on a test flight on 27 December with a dummy payload but had its engine failure causing it to lose its specified above-ground orbit.

Extension of the work of the International Space Station

The US administration directed NASA agency To enable the use of the International Space Station until 2030, and to continue working with its international partners to achieve this end for the next six years.

Hubble is a legend in space

The Hubble Space Telescope has achieved more than a billion seconds in existence in space, which is equivalent to approximately 31.7 years. The Historical Observatory passed the billion-second mark on New Year’s Day (January 1); Hubble was launched aboard the space shuttle Discovery on April 24, 1990. Hubble is a joint mission of NASA and the European Space Agency (ESA).

Strange signals from space

To locate and study planets outside our solar system, astronomers use spacecraft such as NASA’s TESS satellite to collect data on them, but in a new study, researchers used TESS data in a different way.

They used TIS to find out what could cause strange signals to pick up and dim from an object they named TIS 40079922. The TESS satellite is well-equipped to study the brightness of stars because that’s how it detects planets passing in front of their stars.
