LONDON:
Scientists, using data from NASA telescopes, have spotted two
supermassive black holes, located at the centres of galaxies close to
our Milky Way, that were hidden behind shrouds of gas and dust until
now.

The highest altitude gravitational wave telescopes in the world with a budget of USD 18.8 million will be set up close to the Actual Control with India.
The first telescope is already under-construction and has been code-named Ngari No 1, said Yao Yongqiang, chief researcher with the National Astronomical Observatories of the Chinese Academy of Sciences. Yongqiang further said that the first telescope is being set up 30 km south of Shiquanhe Town in Ngari Prefecture.
Parts of Nagri is last Tibetan prefecture at China's border with India.
The first telescope is located 5,250 meters above the level of the sea. It will detect and collect precise data on primordial gravitational waves in the Northern Hemisphere.
The telescope is likely to go operational by 2021, state-run Xinhua news agency reported.
In the second phase, a series of telescopes, code-named Ngari No 2 will be located about 6,000 meters above the level of the sea, said Yongqiang.
Yongqiang didn't spoke as to when will the construction of Ngari No 2 begin. There will be only two phases of Ngari gravitational wave observatory the estimated budget for which has been set up at 130 million yuan (USD 18.8 million).
The Institute of High Energy Physics, National Astronomical Observatories, and Shanghai Institute of Microsystem and Information Technology, among others initiated the project, the report said.
Ngari sports high altitude, clear sky and minimal human activity. It is said to be one of the best spots in the world to detect tiny twists in cosmic light.
Yao said the Ngari observatory will be among the world's top primordial gravitational wave observation bases, alongside the South Pole Telescope and the facility in Chile's Atacama Desert.
Albert Einstein's theory of general relativity first proposed the gravitational waves 100 years ago. But it wasn't until 2016 that scientists with the Laser Interferometer Gravitational-Wave Observatory announced proof of the waves' existence, spurring fresh research interest among the world's scientists.
Last September, China commissioned the world's largest radio telescope in a mountainous region of southwest China's Guizhou Province to search for more strange objects space, gain better understand the origin of the universe and to boost the global hunt for extraterrestrial life.
The installation of the telescope's main structure -- a 4,450-panel reflector as large as 30 football pitches was built at unique valley in Guizhou Province.

Scientists discover dark matter lost since birth of universe

Moscow: Scientists, for the first time, have been able to measure the amount of dark matter the Universe has lost since the Big Bang some 13.7 billion years ago.
About five per cent of the elusive dark matter in the universe has been lost till now, they calculated.
The finding is also likely to explain one of the biggest mysteries in physics - why our Universe appears to function in a slightly different way than it did in the years just after the Big Bang. It could also explain the origin of dark matter and how it might evolve or decay in future.
The study could also help astrophysicists explain how the universe has changed over time. The findings may show how the universe's rate of expansion has varied and what happened in the universe's first few hundred thousand years.
Most of the matter in the universe seems to be invisible and largely intangible; it holds galaxies together and only interacts with the more familiar matter hrough its gravitational pull.
"The discrepancy between the cosmological parameters in the modern Universe and the Universe shortly after the Big Bang can be explained by the fact that the proportion of dark matter has decreased," Igor Tkachev, head of the of the Department of Experimental Physics at the Institute for Nuclear Research in Russia told PTI.
"We have now, for the first time, been able to calculate how much dark matter could have been lost and what the corresponding size of the unstable component would be," Tkachev said.
Their study suggests that no more than 5 percent of the current amount of dark matter in the universe, could have been lost since the Big Bang.
According to data from the European Space Agency (ESA)’s Planck space telescope, the proportion of dark matter in the universe is 26.8 per cent, the rest is “ordinary” matter (4.9 per cent) and dark energy (68.3 per cent).
The properties of dark matter could potentially help scientists solve the problem that arose after studying observations from the Planck telescope.
This device accurately measured the fluctuations in the temperature of the cosmic microwave background radiation – the “echo” of the Big Bang.
By measuring these fluctuations, researchers were able to calculate key cosmological parameters using observations of the universe in the recombination era – about 300,000 years after the Big Bang.
But even though the majority of matter predicted to be in the Universe is actually dark, little is known about dark matter - in fact, scientists till now haven't been able to prove that it actually exists.
