The National Oceanic and Atmospheric Administration scientist says the flare is too weak and any light show would be limited to Alaska, Canada, Iceland, Norway and other far northern spots. Lash says the event is unusual but not rare. That's because it is happening during the quiet four-year solar minimum. It's unlikely to cause power or  communication problems  on Earth, nor will many people get a chance to see shimmering auroras. credits:  phys.org

These findings, published in The Astrophysical Journal, increases the number of black holes known at that epoch considerably. Published:  19th March 2019 12:30 PM credits: wireduk WASHINGTON: Astronomers have discovered 83 quasars powered by supermassive black holes 13 billion light-years away from the Earth, from a time when the universe was less than 10 per cent of its present age. "It is remarkable that such massive dense objects were able to form so soon after the Big Bang," said Michael Strauss, a professor at Princeton University in the US. "Understanding how black holes can form in the early universe, and just how common they are, is a challenge for our cosmological models," Strauss said in a statement. These findings, published in The Astrophysical Journal, increases the number of black holes known at that epoch considerably, and reveals, for the first time, how common they are early in the universe's history. In addition, it provides new insight into th...

Until now, we have read in our science books or even if searching on Google, the answer suggests that Venus is the closest neighbor to Earth. But, now, scientists have made some shocking revelations suggesting that  Mercury  is indeed the  closest planet  to the Earth. Presenting their outcomes in magazine Physics today, scientists from NASA, Los Alamos National Lab, and the U.S. Army, proposed a new model of the planets’ orbit shuffles things around, calculating that Earth’s closest neighbor, on average, is actually Mercury. In fact, it says that every other planet in the solar system’s nearest neighbor is Mercury as well. Normally, we calculate the average distance from the planet to the Sun. The  Earth ’s average distance is 1 astronomical unit ...

This discovery, according to the team, could open up avenues for further studies regarding an alternate theory suggesting radio sources to be powered outside the power law. Radio galaxies are a small subset of galaxies that emit exceptionally powerful emissions at radio frequencies. In a first, a team of Indian astronomers has discovered some sources in the universe capable of emitting radio waves in a never-before-known mechanism, using the Giant Metrewave Radio Telescope (GMRT) located at Khodad in Junnar, about 80 km from Pune. Advertising The team, led by TIFR-National Centre for Radio Astronomy (NCRA), which operates the GMRT, said they found a rare source named ‘Extremely Inverted Spectrum Extragalactic Radio Sources’. This discovery, according to the team, could open up avenues for further studies regarding an alternate theory suggesting radio sources to be powered outside the power law. “In case of special cluster sources, the magnetic flux drops to low frequencies and capturin...
