    Massive radio survey reveals our universe's structure at the largest scales

    I find it curious that to my eye the resultant image of the movement looks so much like the yin-yang symbol. The ESA's GAIA telescope team provided an image of the 3D relative velocities within the Milky Way. May well be just an artifact of the human ability to see patterns that make sense of...

    X-rays reveal secret gas in huge and distant galaxy cluster

    If something on Earth was "... suffused by huge amounts of gas that can reach scorching temperatures up to 100 million degrees Celsius" it would be described as a plasma, the purview of plasma physicists and electrical engineers. They would potentially link the phenomenon with the associated...

    Traffic jams' around Uranus could solve the mystery of its weak radiation belts

    You may wish to edit the line "...Uranus is also only one of two planets in the solar system (the other is Venus) that rotates around the sun in the opposite direction to all the other planets." I believe you mean they are the only two planets to rotate around their axis, not the sun, in the...

    Space mysteries: Do all planets have magnetic fields?

    "Deeper still the rotation appears to be consistent with solid-body rotation." Michael J Thompson, Helioseismology and the Sun's interior, Astronomy & Geophysics, Volume 45, Issue 4, August 2004, Pages 4.21–4.25 As far as the piezo part of my speculating, it might be worth your while checking...

    Space mysteries: Do all planets have magnetic fields?

    Okay, so I may be putting my hand up for a "kook of the day" badge, but I have a different hypothesis for the generation of planetary magnetic fields. The use of seismology has given us insight into the makeup of the Earth's core, being a reasonably solid crystallising iron with some nickel...

    NASA's Voyager 1 spacecraft finally phones home after 5 months of no contact

    I had to pause when I first read it, but I believe they were referring to the 35 years it took from launch in 1977 to hitting interstellar space in 2012. That's why they then mention V2 taking an extra 6 years, till 2018 to leave the sun's influence.
