An international scientific team on Wednesday announced a milestone in astrophysics - China Portable Bluetooth Audio lamp manufacturer the first-ever photo of a black hole - using a global network of telescopes to gain insight into celestial objects with gravitational fields so strong no matter or light can escape.The research was conducted by the Event Horizon Telescope (EHT) project, an international collaboration begun in 2012 to try to directly observe the immediate environment of a black hole using a global network of Earth-based telescopes. The announcement was made in simultaneous news conferences in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo.The image reveals the black hole at the centre of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster.

This black hole resides about 54 million light-years from Earth.Black holes, phenomenally dense celestial entities, are extraordinarily difficult to observe despite their great mass. A black hole’s event horizon is the point of no return beyond which anything - stars, planets, gas, dust and all forms of electromagnetic radiation - gets swallowed into oblivion."This is a huge day in astrophysics," said US National Science Foundation Director France Córdova. "We’re seeing the unseeable."The fact that black holes do not allow light to escape makes viewing them difficult. The scientists look for a ring of light - disrupted matter and radiation circling at tremendous speed at the edge of the event horizon - around a region of darkness representing the actual black hole. This is known as the black hole’s shadow or silhouette.The project’s researchers obtained the first data in April 2017 using telescopes in the US states of Arizona and Hawaii as well as in Mexico, Chile, Spain and Antarctica. Since then, telescopes in France and Greenland have been added to the global network. The global network of telescopes has essentially created a planet-sized observational dish.

Mumbai: After torrential rains on Saturday, the maximum city witnessed a rather dry spell with moderate rains recorded on Sunday. The Indian Meteorological Department (IMD) has withdrawn the heavy rains warning predicted for Mumbai till Monday, officials stated that the intensity of rain is expected to reduce.According to IMD, Mumbai is likely to receive only light rain in few parts of the city and the rainfall activity is not expected to increase in coming days. "The monsoon current over Mumbai has slightly weakened. As there are no heavy spells expected for Mumbai in the next few days, we have withdrawn heavy rainfall warning," said Ajay Kumar, senior scientist, IMD.With the arrival of monsoon in the city, in the last 24-hours since 8 am on Saturday, Mumbai’s Colaba observatory recorded 164mm of rainfall, while Santacruz observatory recorded 100.1mm of rainfall.

The city area of Mumbai received an average 134mm rainfall between 8 am and 9 pm on Saturday; followed by 87mm in the western suburbs and 54mm in the eastern suburbs. Areas like B ward, Parel, Dharavi and F South Ward received the highest rainfall during this period.As per Skymet Weather, a private weather forecasting agency, the off-shore trough will extend from North Maharashtra to Kerala coast. Heavy to very China Solar LED tube lamp manufacturer heavy rains to occur over coastal parts of Maharashtra, Goa, Coastal Karnataka and Kerala. Light to moderate rains may also occur over Telangana. Light rains are likely over rest of Southern Peninsula. Due to the advancement of southwest monsoon, light to moderate rains to occur over many places of Madhya Pradesh, Chhattisgarh and Vidarbha.

Scientists have discovered Sun-like twin stars, one of which may have ingested a dozen or more of its own rocky planets, located 350 China Solar LED light guide strip manufacturer light years from Earth.The planet-devouring star was named star after Titan Kronos - a mythological character that devoured his children, including Poseidon (better known as the planet Neptune), Hades (Pluto) and three daughters.The twin star was named after Kronos lesser-known brother Krios. Their official designations are HD 240430 and HD 240429.Researchers from Princeton University in the US confirmed that the widely separated pair about 350 light years from Earth are in fact a binary pair. They also observed Kronos strikingly unusual chemical abundance pattern.Other co-moving star pairs have had different chemistries, but none as dramatic as Kronos and Krios, said Semyeong Oh, a graduate student at Princeton."Most stars that are as metal-rich as Kronos have all the other elements enhanced at a similar level, whereas Kronos has volatile elements suppressed, which makes it really weird in the general context of stellar abundance patterns," she said.In other words, Kronos had an unusually high level of rock-forming minerals, including magnesium, aluminum, silicon, iron, chromium and yttrium, without an equally high level of volatile compounds - those that are most often found in gas form, like oxygen, carbon, nitrogen and potassium.

Kronos and Krios are far enough apart that some astronomers have questioned whether the two were in fact a binary pair.Both are about four billion years old, and like our own, slightly older sun, both are yellow G-type stars. They orbit each other infrequently, on the order of every 10,000 years or so. Binary stars should have matching radial velocities.Finding matching velocities in the new study supported the theory that Kronos and Krios, though two light years apart, were a binary set. Then the researchers noticed the extreme chemical differences between them.
