[13 May 2022] Lia Medeiros, co-lead of the EHT Gravitational Physics Working Group, talks to CNN about capturing the first image of the massive black hole at the center of the Milky Way galaxy. #CNN #News
-
[12 May 2022] Humanity’s first image of the central supermassive black hole at the heart of the Milky Way Galaxy has been revealed by the Event Horizon Telescope collaboration. We chat with University of Melbourne PhD student Aman Chokshi who works with the EHT in Antarctica about this historic event.
-
A black hole is a region of spacetime where gravity is so strong that nothing – no particles or even electromagnetic radiation such as light – can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. Although it has an enormous effect on the fate and circumstances of an object crossing it, it has no locally detectable features according to general relativity.
-
A Dyson sphere is a hypothetical megastructure that completely encompasses a star and captures a large percentage of its solar power output. The concept is a thought experiment that attempts to explain how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone.
-
Sagittarius A* (/?e? st??r/ AY star), abbreviated Sgr A* (/?sæd? ?e? st??r/ SAJ AY star) is the supermassive black hole at the Galactic Center of the Milky Way. It is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, visually close to the Butterfly Cluster (M6) and Lambda Scorpii.

DUBAI, March 11 (Reuters) - Crypto firms in the United Arab Emirates (UAE) are being deluged with requests to liquidate billions of dollars of virtual currency as Russians seek a safe haven for their fortunes, company executives and financial sources said. Some clients are using cryptocurrency to invest in real estate in the UAE, while others want to use firms there to turn their virtual money into hard currency and stash it elsewhere, the sources said

The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The common name comes from William Parsons, 3rd Earl of Rosse, who observed the object in 1842 using a 36-inch (91 cm) telescope and produced a drawing that looked somewhat like a crab.
-
Messier 87 (also known as Virgo A or NGC 4486, generally abbreviated to M87) is a supergiant elliptical galaxy with several trillion stars in the constellation Virgo. One of the most massive galaxies in the local universe, it has a large population of globular clusters — about 15,000 compared with the 150–200 orbiting the Milky Way — and a jet of energetic plasma that originates at the core and extends at least 1,500 parsecs (4,900 light-years), traveling at a relativistic speed. It is one of the brightest radio sources in the sky and a popular target for both amateur and professional astronomers.

"Time Trumpet" is a six episode satirical television comedy series which aired on BBC Two in August 2006. The series was written by Armando Iannucci, Roger Drew and Will Smith in a similar manner to Iannucci's earlier one-off programmes, "2004: The Stupid Version" and "Clinton: His Struggle with Dirt". One sketch was later spun off by network in Ireland, RTÉ, into the cult television series "Soupy Norman", in May 2007. "Time Trumpet" is set in the year 2031, and is a retrospective documentary on the first thirty years of the twenty-first century. Actors and actresses played the parts of 'today's stars' thirty years on, who were interviewed as part of the show.
-
[3 May 2022] Using a new technique Australian astronomers have led an international team in discovering one of the most luminous pulsars known to date, located in our neighbouring galaxy, the Large Magellanic Cloud. Until now, the bright object has somehow avoided all detection.
-
A pulsar (from pulsating radio source) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing toward Earth (similar to the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission.
-
A neutron star is the collapsed core of a massive supergiant star, which had a total mass of between 10 and 25 solar masses, possibly more if the star was especially metal-rich. Except for black holes and some hypothetical objects (e.g. white holes, quark stars, and strange stars), neutron stars are the smallest and densest currently known class of stellar objects.
-
The Parkes Observatory (also known as "The Dish") is a radio telescope observatory, located 20 kilometres (12 mi) north of the town of Parkes, New South Wales, Australia. It was one of several radio antennae used to receive live television images of the Apollo 11 Moon landing. Its scientific contributions over the decades led the ABC to describe it as "the most successful scientific instrument ever built in Australia" after 50 years of operation.
-
Jodrell Bank Observatory (/?d??dr?l/) in Cheshire, England, hosts a number of radio telescopes as part of the Jodrell Bank Centre for Astrophysics at the University of Manchester. The observatory was established in 1945 by Bernard Lovell, a radio astronomer at the university, to investigate cosmic rays after his work on radar in the Second World War. It has since played an important role in the research of meteoroids, quasars, pulsars, masers and gravitational lenses, and was heavily involved with the tracking of space probes at the start of the Space Age.
-
War of the Worlds is a television series produced by Fox Networks Group and StudioCanal-backed Urban Myth Films. The series is created and written by Howard Overman, and directed by Gilles Coulier and Richard Clark. The series is a loose adaptation of The War of the Worlds, an 1898 novel by H. G. Wells about Earth coming to terms in the wake of a sudden Martian invasion.

The Miller–Urey experiment (or Miller experiment) was a chemical experiment that simulated the conditions thought at the time (1952) to be present on the early Earth and tested the chemical origin of life under those conditions. The experiment at the time supported Alexander Oparin's and J. B. S. Haldane's hypothesis that putative conditions on the primitive Earth favored chemical reactions that synthesized more complex organic compounds from simpler inorganic precursors. Considered to be the classic experiment investigating abiogenesis, it was performed in 1952 by Stanley Miller, supervised by Harold Urey at the University of Chicago, and published the following year.
