Astronomers have discovered evidence for an extraordinarily long jet of particles coming from a supermassive black hole in the early universe, using NASA’s Chandra X-ray Observatory.

If confirmed, it would be the most distant supermassive black hole with a jet detected in X-rays. Coming from a galaxy about 12.7 billion light-years from Earth, the jet may help explain how the biggest black holes formed at a very early time in the universe’s history.

The source of the jet is a quasar — a rapidly growing supermassive black hole — named PSO J352.4034-15.3373 (PJ352-15 for short), which sits at the center of a young galaxy...

A Giant, Sizzling Planet may be Orbiting the Star Vega

Astronomers have discovered new hints of a giant, scorching-hot planet orbiting Vega, one of the brightest stars in the night sky. The research, published this month in The Astrophysical Journal, was led by University of Colorado Boulder student Spencer Hurt, an undergraduate in the Department of Astrophysical and Planetary Sciences.

It focuses on an iconic and relatively young star, Vega, which is part of the constellation Lyra and has a mass twice that of our own sun. This celestial body sits just 25 light-years, or about 150 trillion miles, from Earth—pretty close, astronomically speaking.

Scientists can also see Vega with telescopes even...

Most Distant Quasar with Powerful Radio Jets discovered

undefined
With the help of the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a “radio-loud” quasar — a bright object with powerful jets emitting at radio wavelengths — that is so far away its light has taken 13 billion years to reach us. The discovery could provide important clues to help astronomers understand the early Universe.

Source of Hazardous High-Energy Particles Located in the Sun

coronal mass ejection

The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the first time by researchers at UCL and George Mason University, Virginia, USA.

These particles are highly charged and, if they reach Earth’s atmosphere, can potentially disrupt satellites and electronic infrastructure, as well as pose a radiation risk to astronauts and people in airplanes. In 1859, during what’s known as the Carrington Event, a large solar storm caused telegraphic systems across Europe and America to fail. With the modern world so reliant on electronic infrastructure, the potential for harm is much greater.

To minimise the danger, scientists are seeking to understand how these streams of particles are produced so ...
