Meg Lanning: 'I wanted to dig a hole and jump in'

“Are you going to have nightmares…” “Yes!” The question wasn’t even fully formed yet and Meg Lanning had provided the answer. No, she wasn’t going to sleep well after hitting the catch that would give footer Alana King a hat-trick, her country’s second in the women’s T20Is. To be honest, Lanning, the Australia captain, was a kind person about the situation, from burying his face in the Edgbaston grass there, where if you gave him 99 equal chances, he would take it, to grimacing in the background as reporters questioned King a few yards away. afterwards about the incident and then confronted the same reporters, knowing very well what was going to happen. “I’m going to have nightmares,” Lanning said. “I wanted to dig a hole and jump into it as fast as I could. I tried my best and I dropped it.” Softening the blow somewhat was the fact that Australia had one foot in the Commonwealth Games semi-finals with Barbados 53 for 8 at the time. Barbados managed just 64 before being blown away.

Sneaky black hole discovery explains star death, black hole formation, and gravitational waves

Calçada, CC BY There is always something new and exciting going on in the field of black hole research. Albert Einstein first published his book explaining the general theory of relativity—which postulates black holes—in 1922. One hundred years later, astronomers captured the true image of the black hole at the center of the Milky Way. In a recent paper, a team of astronomers describes another exciting new discovery: the first “dormant” black hole observed outside a galaxy. I am an astrophysicist who has studied black holes—the densest objects in the universe—for nearly two decades. An inactive black hole is a black hole that does not emit detectable light. Because of this, they are notoriously hard to find. This new discovery is exciting because it provides insight into the formation and evolution of

Origin of ‘ghost particles’ DISCOVERED: Tiny bodies that pass through our body and planet undetected emitted from galactic cores fed by supermassive black holes in outer space ‘Ghost particles,’ or neutrinos, are particles that originate from outer space These particles have no mass and hardly interact with matter Scientists believe they came from the core of a galaxy that was fed by a supermassive black hole Blazars are known for emitting bright beams of light and wind and are thought to also produce cosmic rays By Stacy Liberatore For Dailymail.com Published: 2:04pm EDT, July 25, 2022 | Updated: 2:18 p.m. EDT, 25 July 2022 Extraterrestrial ‘ghost particles’ likely originate from the cores of galaxies fed by supermassive black holes, according to a new study that could unravel the mystery of subatomic particles that formed before the universe. Ghost particles, or neutrinos, have baffled scientists since they were firs

Calcada / Handout via REUTERS WASHINGTON-Astronomers have spotted in a galaxy adjacent to the Milky Way what they call a cosmic “needle in a haystack”-a black hole that is not only classified as dormant, but also appears to have been born without a stellar death explosion. Researchers said Monday this one differs from all other known black holes in that it is “quiet X-ray”—it doesn’t emit strong X-ray radiation that indicates it devours nearby matter with a strong gravitational pull—and that it doesn’t. born in the explosion of a star called a supernova. Black holes are extremely dense objects with such strong gravity that not even light can escape. This one, with a mass at least nine times that of the sun, was detected in the Tarantula Nebula region of the Large Magellanic Cloud galaxy and is located about 160,000 light

First dormant black hole discovered is thought to be a 'needle in a haystack'

Astronomers have seen in the galaxy adjacent to our Milky Way what they call the cosmic “needle in the haystack” – a black hole that is not only classified as dormant but appears to have been born without the explosion of a dying star. Researchers said Monday this one differs from all other known black holes in that it is “quiet X-ray” – it doesn’t emit the intense X-ray radiation that indicates it devours nearby matter with a strong gravitational pull – and it doesn’t. born in the explosion of a star called a supernova. Black holes are extremely dense objects with such strong gravity that even light cannot escape. This one, with a mass at least nine times that of our sun, was detected in the Tarantula Nebula region of the Great Magellanic Cloud galaxy and is located about 160,000 light-years from Earth. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). A very luminous and hot blue star with a mass about 25 times that of the sun orbits this bl

Huge Black Hole Existed Before Universe's First Star (Weekend Feature)

The discovery of black holes was the first collision of quantum gravity with general relativity. In 2019, astrophysicists at the University of Western Ontario discovered proof for the direct formation of black holes that need not arise from stellar remnants. The production of black holes in the early universe, which formed from massive seeds aided by the gravitational field immediately after the Big Bang, provided scientists with an explanation for what appeared to be extremely massive black hole anomalies at a very early stage in the history of our universe. Supermassive black holes formed very, very quickly in the early universe over a very, very short period of time and then suddenly, they stopped. Shantanu Basu and Arpan Das from the Western Department of Physics & Astronomy developed an explanation for the observed distribution of mass and luminosity of supermassive black holes, for which there was no scientific explanation before. They concluded that su

Earth Sky | Whooshing sound! Fast star orbiting the Milky Way's black hole

This image shows the center of our Milky Way galaxy. It shows the position of stars in the so-called S star cluster, a small group of high-speed stars orbiting our Milky Way’s central black hole (at the black cross). Speedy star S4716 has set a new record as the fastest known of all these stars. Image via Peissker et al. Fast star orbiting the Milky Way’s black hole Scientists in Europe said on July 5, 2022 that they had found the fastest star known to orbit a black hole. And not just any black hole… it orbits Sagittarius A*, the giant black hole at the center of our Milky Way galaxy. Our central black hole weighs about 4 million times the mass of our sun. The newly discovered star is called S4716. It reaches an orbital speed of 5,000 miles per second (8,000 kps) around the black hole, or about 5,000 times faster than the fastest fighter jet. Imagine seeing star – a huge ball of turbulent gas that glows on its own – shooting at this speed! By the way, on the other hand, ou

We Have New Record For Fastest Star Enlarging Supermassive Black Hole

Image
A newly discovered star is so close to the center of our galaxy’s supermassive black hole that it completes an orbit in just four years. It is the shortest orbit for any of the stars around Sagittarius A*. This is an oval-shaped journey around a black hole that takes the star to an orbital speed of more than 2.5 percent of the speed of light. This discovery adds exciting new information about the strange dynamics of the center of the Milky Way. Although the center of our galaxy is quite quiet compared to other galaxies, the environment around Sgr A* is an extreme place. Black holes are monsters, which have a mass about 4 million times the mass of the Sun. Before astronomers confirmed its existence with live images, scientists deduced its existence and calculated its mass based on the star locked in orbit around Sgr A*. The star, called S2, is just one of a group of stars known as S-stars, which follow a long, sharp elliptical orbit around Sgr A*, with a black hole at one end of the

A star orbits the Milky Way's black hole at 18 million miles per hour

A newly discovered star, now called S4716, is moving at 5,000 miles (8,000 km) per second around the black hole at the center of our galaxy, the Milky Way, space.com reported. The vast expanse of our universe means that astronomers are always discovering something they’ve never seen before. Earlier this week, astronomers spotted two asteroids the size of a bus heading for Earth, which will pass just a quarter of the distance that separates the Moon from us. In addition to asteroids, our galaxy is also attracting the attention of astronomers looking for signs of other planets that support life. Right at the center of the Milky Way, there is a supermassive black hole dubbed Sagittarius A* or Sgr A* and S4716 orbits this black hole at high speed. What we know about S4716 From observations made so far, we know that at 5,000 miles (8,000 km) per second or 18 million miles (29 million km) per hour, S4716 is the fastest star orbiting Sgr A*. It completes an orbit around a black hole with
