The gentle nudge of a neutrino (or a neutrino giving some momentum to the nucleus by exchanging a Z boson with one of the nucleus' quarks, after which the nucleus loses that energy by emitting a photon) finally observed after 43 years.
If WASP-121b were any closer to its host star, it would be ripped apart by the star's gravity. The top of the planet's atmosphere is heated to 2,500 degrees Celsius -- so hot that iron can exist only as a gas, instead of a solid.
Exactly how the stratosphere can remain intact at such a high temperature is something the researchers want to investigate.
New experiments with helium-3 in a magnetic confinement tokamak have produced exciting results for the future of fusion energy, including a tenfold increase in ion energy.
4 millions miles may seem like a large distance but in space it's truly a close call. Tomorrow a 3 mile wide asteroid called Florence will make a "close" encounter.
Fossil footprints challenge established theories of human evolution
Quote:
Newly discovered human-like footprints from Crete may put the established narrative of early human evolution to the test. The footprints are approximately 5.7 million years old and were made at a time when previous research puts our ancestors in Africa -- with ape-like feet.
It should be visible through a telescope if you know where to look. Too dim to see without aid though, magnitude 6.5 is about the limit of naked eye viewing (under ideal conditions, perfect dark, dark adapted eyes, no light pollution). I think this is magnitude 9 or so.
Asteroid 2004 MN4 is supposed to come within 35,000km of Earth in 2029 (closer than some satellites, close enough it's orbit will be significantly impacted by Earth's gravity), that'll be visible, and a once in a lifetime view.

But certainty is an absurd one.

Is that the doomsday asteroid that'll return and smack the earth 7 years later if it goes threw some sort of gravity keyhole?
A Canadian effort to build one of the most innovative radio telescopes in the world will open the universe to a new dimension of scientific study. The Honourable Kirsty Duncan, Minister of Science, today installed the final piece of this new radio telescope, which will act as a time machine allowing scientists to create a three-dimensional map of the universe extending deep into space and time.
The Canadian Hydrogen Intensity Mapping Experiment, known as CHIME, is an extraordinarily powerful new telescope. The unique “half-pipe” telescope design and advanced computing power will help scientists better understand the three frontiers of modern astronomy: the history of the universe, the nature of distant stars and the detection of gravitational waves.
By measuring the composition of dark energy, scientists will better understand the shape, structure and fate of the universe. In addition, CHIME will be a key instrument to study gravitational waves, the ripples in space-time that were only recently discovered, confirming the final piece of Einstein’s theory of general relativity.
Cassini is no more. At 10:31 according to its own clock, its thrusters could no longer hold its radio antenna pointed at Earth, and it turned away. A minute later, it vaporized in Saturn’s atmosphere.
Would have been awesome if Calgary / Red Deer / Edmonton got in on this fun.... damn. I wonder if there was an Alberta submission. This is the kind of tech innovation we should aggressively be going after.
I wasn't sure where to put this, so it appears hear as well as in the "Godless Apostate" thread. I claim the right to tag this as "science news" especially since I am presently working with a team of physicists in Berlin on this project.
I gave an interview a few weeks ago to a journalist from the Times of Israel about the recent scourge of manuscript forgeries purported to belong to the Dead Sea Scrolls:
