Astronomers Have Detected the Brightest Fast Radio Burst Ever Seen. Still No Idea What’s Causing Them – Universe Today Space and Astronomy news Source: www.universetoday.com/138807/astronomers-detected-brightest-fast-radio-burst-ever-seen-still-no-idea-whats-causing/

In a study published March 14 in The Monthly Notices of the Royal Astronomical Society, astronomers announced the discovery that all galaxies rotate about once every billion years, no matter their size or mass.  “It’s not Swiss watch precision,” said Gerhardt Meurer, an astronomer from the International Centre for Radio Astronomy Research (ICRAR), in a press…

Milky Way neighbours “ripped out” by colliding galaxy | Cosmos Stars currently orbiting the Milky Way were violently ripped from our own galaxy by an invading satellite galaxy, astronomers have discovered. When galaxies pass close by to each other, massive gravitational forces fling stars, dust and gas around like a giant cosmic blender. These interactions…

In 1929 Edwin Hubble surprised many people – including Albert Einstein – when he showed that the universe is expanding. Another bombshell came in 1998 when two teams of astronomers proved that cosmic expansion is actually speeding up due to a mysterious property of space called dark energy. This discovery provided the first evidence of…

Great article from Professor Karl Glazebrook of Swinburne Uni. Signal detected from the first stars in the universe, with a hint that dark matter was involved Signals from the first stars to form in the universe have been picked up by a table-sized detector in a west Australian desert. The find also hints at an early…

Interesting results from Hubble suggesting confirmation of a discrepancy in the rate of the expansion of the Universe.  Fresh Evidence for New Physics in the Universe The most precise measurements of the expansion rate of the universe are forcing astronomers to consider something unexpected at work in the universe.

  Astronomers Shed Light on Formation of Black Holes and Galaxies W. M. Keck Observatory Latest findings using the W. M. Keck Observatory on Maunakea, Hawaii increase scientific understanding of how powerful winds generated by supermassive black holes impact and regulate the growth of 3C 298 Quasar Host Galaxy.

Fast Radio Burst (FRB) might actually be on the verge of being solved.   Astronomers may be closing in on source of mysterious fast radio bursts Pulses may be from a neutron star cocooned by a strong magnetic field – though experts are not ruling out more unorthodox explanations such as alien ships Source: www.theguardian.com/science/2018/jan/10/astronomers-may-be-closing-in-on-source-of-mysterious-fast-radio-bursts

Picked up from twin instruments, Ligo and Vigo.  New gravitational wave detection shows shape of ripples from black hole collision For the first time, astronomers have detail on the 3D pattern of warping that occurs when black holes with masses of 31 and 25 times that of the sun collide Source: www.theguardian.com/science/2017/sep/27/new-gravitational-wave-detection-shows-shape-of-ripples-from-black-hole-collision-ligo-virgo

Details on a the source of a Fast Radio Burst (FRB) Exploring a Fast Radio Burst in Three Dimensions Exploring a Fast Radio Burst in Three Dimensions Gemini Observatory provides critical rapid follow up observations of a Fast Radio Burst – one of modern astronomy’s greatest enigmas. These observations provide the first details on a…

At least, a better way to simulate the accretion of Supermassive Black Hole at the Center of the Milky Way. A Better Way to Simulate Accretion of the Supermassive Black Hole at the Center of the Milky Way Scientists at Princeton University and the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed…

And it’s from outside the Milky Way too. Astronomers Have Traced The Source of The Most Powerful Radio Signal Ever Received From Space Scientists have observed the most powerful fast radio burst (FRB) ever – an intensely brilliant burst of radiation emanating from outside our own Milky Way galaxy.
