A meteorite expired at & # 39; one month in & # 39; e total eclipse

If you do not get it, try again. That's the philosophy of José María Madiedo, an astronomer at the University of Huelva, who has tried more than 10 years to complete a meteorite in & nbsp; a month in & # 39; a month end. He got it yesterday, in "Superluna de Sangre del Lobo".

The long waiting eclipse just woke up. Millions of people see the night sky to see the impressive coffee red color that contains the natural satellite of our planet. The uncertain thing is that, as the January 21 window appeared, a few judges found a small white page in "online" connection. Some suspect the block was caused by a meteorite, and it turned out to be right.

José Madiedo confirmed these suspicions. According to tweeted, a linear influence gained at 5:41 peninsula Spanish time. One photo clearly has a yellowish white spot in the top link quadrant of & # 39; a month, in & # 39; a whole fifth phase.

Astronomers had previously recorded in the month, but this is the first time in & # 39; A month's decision, a profit that has taken 20 years to become a reality. They began systematically reviewing the striking blocks in 1997, an effort that became the Moon Impact Detection and Analysis System, or MIDAS, a survey by the University of Huelva and the Institute of Astrophysics of Andalucia. Madiedo joined the project in 2008. When using astronomical data from multiple observations, MIDAS identifies the moment a meteor shower hits the dark parts of a month's surface.

"We observe the month of the night region to identify the impact. In this way, these blocks are well-contrasted with the dancer's background," Madiedo explained to Gizmodo. "Generally, we will check five days before and five days after the new month. We also see monumental hermits, because in these light connections the moonflower is dark."

The telescopes that are used by MIDAS with a high-sensitivity video camera are stored and continually updated in any observation session. These videos are then analyzed with software that automatically shines the month impact and calculates the position at month's time. Madiedo says the system can block the moment of an impact with a accuracy of ± 0.001 seconds. Since 2015, team photometric filters apply to some of their telescopes, making it possible to determine the temperature of these blocks.

MIDAS never had a meteorite capability (up to yesterday) in total month's eclipse, but it was not for abuse attempts. Madiedo does not know that the exact coverage of the eclips it has MIDAS has so far checked, but he said they all checked that it was visible since the study began. However, other groups try to find light bulbs on Monday, say Madiedo, but no one has been successful so far.

Normally, Madiedo's team has used four telescope to save the month, but this time they decided to use it. Recipient work was required to configure and check the new tools.

"In total I spent about two days without sleep, like the add-on time at the mouths," Madiedo told Gizmodo. "But I made an extra effort to make the new telescope to" "I had the feeling that this time would happen, and I didn't want to have a flash of influence. An instrument had a technical problem and failed. I was lost the window class was finally, but when the automatic vacation software chose me from the lightning lightning, I jumped out of my chair, it was a very exciting time to 39; I knew I had never registered. "

"Do the automatic vacation software expect me from light blocks, I jumped out of the chair"

Madiedo says a leaflet of this magnitude happens once every 7-10 days. His team has not yet analyzed all the data, but a provisional estimate is that the object, probably a small asteroid, had a mass of about 10 kilos.

By studying these blocks, scientists can get better statistics about the increasing power outputs and, hence, the number of times the earth is reached by objects of the same size.

On an increased note, a The recent study suggests that the asteroid of large asteroid effects on earth increased by 290 million years ago. This conclusion was reached by examining the history of influx craters on a month floor. Our moon looks nothing like earth, but if it comes to heavenly consequences, we have a shared history.
