Scientists discover a huge black hole, 700 million light-years away, that eats about one sun per day . . . . J2157, which is the fastest-growing black hole known to humans, is amazingly large and extremely hungry, a new research conducted by an international team of astronomers has found The results of the study were published in Monthly Notices of the Royal Astronomical Society. The research, led by The Australian National University found that the black hole is 34 billion times the mass of our sun and eats nearly the equivalent of one sun every day. One of the authors of the study Dr Christopher Onken said that the black hole’s mass is also about 8,000 times bigger than the black hole at the centre of the Milky Way. He went on to add, "If the Milky Way’s black hole wanted to grow that fat, it would have to swallow two-thirds of all the stars in our Galaxy.” J2157 was first discovered by the team in 2018. Dr Onken said that researchers are looking at it at a time when the universe was only 1.2 billion years old, adding that it is the biggest black hole that has been weighed in that early period of the Universe. According to a report in CNET, Fuyan Bian of the European Southern Observatory (ESO), who is also part of the team, said that how much black holes can swallow depends on how much mass they already have. "So, for this one to be devouring matter at such a high rate, we thought it could become a new record holder," Bian went on to add. As per the report, the team used ESO's Very Large Telescope on Chile to get the data on the black hole's mass. The black hole is hidden within the galaxy Holm 15A, which is 700 million light-years away from earth.

Asteroid Day (also known as International Asteroid Day) is an annual global event which is held on the anniversary of the Siberian Tunguska event that took place on June 30, 1908, the most harmful known asteroid-related event on Earth in recent history. The United Nations has proclaimed it be observed globally on June 30 every year in its resolution. Asteroid Day aims to raise awareness about asteroids and what can be done to protect the Earth, its families, communities, and future generations from a catastrophic event. For example, 2014 HQ124, discovered April 23, 2014, went past 1,250,000 km from Earth the same year, June 8th, only 46 days after discovery, and 2015 TB145, went past at 490,000 km only 21 days after its discovery.

25 Years in Space for ESA & NASA’s Sun-Watching SOHO

A quarter-century ago, the Solar and Heliospheric Observatory (SOHO) launched to space. Its 25 years of data have changed the way we think about the Sun — illuminating everything from the Sun’s inner workings to the constant changes in its outermost atmosphere.

SOHO — a joint mission of the European Space Agency and NASA — carries 12 instruments to study different aspects of the Sun. One of the gamechangers was SOHO’s coronagraph, a type of instrument that uses a solid disk to block out the bright face of the Sun and reveal the relatively faint outer atmosphere, the corona. With SOHO’s coronagraph, scientists could image giant eruptions of solar material and magnetic fields, called coronal mass ejections, or CMEs. SOHO’s images revealed shape and structure of CMEs in breathtaking detail.

These solar storms can impact robotic spacecraft in their path, or — when intense and aimed at Earth — threaten astronauts on spacewalks and even disrupt power grids on the ground. SOHO is particularly useful in viewing Earth-bound storms, called halo CMEs — so called because when a CME barrels toward us on Earth, it appears circular, surrounding the Sun, much like watching a balloon inflate by looking down on it.

Before SOHO, the scientific community debated whether or not it was even possible to witness a CME coming straight toward us. Today, SOHO images are the backbone of space weather prediction models, regularly used in forecasting the impacts of space weather events traveling toward Earth.

Beyond the day-to-day monitoring of space weather, SOHO has been able to provide insight about our dynamic Sun on longer timescales as well. With 25 years under its belt, SOHO has observed a full magnetic cycle — when the Sun’s magnetic poles switch places and then flip back again, a process that takes about 22 years in total. This trove of data has led to revolutions in solar science: from revelations about the behavior of the solar core to new insight into space weather events that explode from the Sun and travel throughout the solar system.

Data from SOHO, sonified by the Stanford Experimental Physics Lab, captures the Sun’s natural vibrations and provides scientists with a concrete representation of its dynamic movements.

The legacy of SOHO’s instruments — such as the extreme ultraviolet imager, the first of its kind to fly in orbit — also paved the way for the next generation of NASA solar satellites, like the Solar Dynamics Observatory and STEREO. Even with these newer instruments now in orbit, SOHO’s data remains an invaluable part of solar science, producing nearly 200 scientific papers every year.

Relatively early in its mission, SOHO had a brush with catastrophe. During a routine calibration procedure in June 1998, the operations team lost contact with the spacecraft. With the help of a radio telescope in Arecibo, the team eventually located SOHO and brought it back online by November of that year. But luck only held out so long: Complications from the near loss emerged just weeks later, when all three gyroscopes — which help the spacecraft point in the right direction — failed. The spacecraft was no longer stabilized. Undaunted, the team’s software engineers developed a new program that would stabilize the spacecraft without the gyroscopes. SOHO resumed normal operations in February 1999, becoming the first spacecraft of its kind to function without gyroscopes.

SOHO’s coronagraph have also helped the Sun-studying mission become the greatest comet finder of all time. The mission’s data has revealed more than 4,000 comets to date, many of which were found by citizen scientists. SOHO’s online data during the early days of the mission made it possible for anyone to carefully scrutinize a image and potentially spot a comet heading toward the Sun. Amateur astronomers from across the globe joined the hunt and began sending their findings to the SOHO team. To ease the burden on their inboxes, the team created the SOHO Sungrazer Project, where citizen scientists could share their findings.

The Emirates Mars Mission is an uncrewed space exploration mission to Mars, which launched the Hope orbiter on 19 July 2020. It will attempt to answer the scientific questions of why Martian atmosphere is losing hydrogen and oxygen into space and the reason behind drastic climate changes of Mars. * * * Tianwen-1 (TW-1) is an interplanetary mission to Mars by the China National Space Administration (CNSA), which launched a robotic spacecraft, which consists of an orbiter, a lander and a rover on 23 July 2020. Its stated objectives are to search for evidence of both current and past life, and to assess the planet's environment. * * * Mars 2020 is a Mars rover mission by @nasa 's Mars Exploration Program that includes the Perseverance rover with a planned launch on 30 July 2020. It will investigate an astrobiologically relevant ancient environment on Mars and investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of past life on Mars, and the potential for preservation of biosignatures within accessible geological materials. * * * ⬇️ Comment down your thoughts ⬇️ https://www.instagram.com/p/CDuyYhPjOWq/?igshid=1t84cckt9siep
