Today’s stories range from Humans making it harder to eavesdrop on possible aliens to Hubble Telescope spots, a stunning galaxy hidden behind the Milky Way, to bottomless black hole exit ramps out of the universe , And much more.
Humans make it harder to listen to possible aliens –Increasing demands for mobile services and wireless internet have congested the radio spectrum, creating interference that can skew data and add “noise” to scientific findings, reports 4NBC Washington.
NASA’s massive new spacecraft built to hunt alien life, reports cNET– “This is the largest NASA spacecraft ever developed for a planetary mission, and in October 2024 it is scheduled to travel to an extraterrestrial world that many scientists deeply believe may harbor extraterrestrial life. It’s called the Clipper and is heading for Europa, Jupiter’s icy moon.
Australian researchers discover the fastest growing black hole in the last 9 billion years–Visible to a backyard astronomer, yet only just discovered, reports Cosmos.com
Hubble Telescope Spots Stunning ‘Hidden Galaxy’ Hidden Behind Our Own Milky Way, reports Elizabeth Howell for Space.com. “If it weren’t for all the interstellar material in the way, IC 342 would be one of the brightest galaxies in the sky.”
James Bardeen, expert in unraveling Einstein’s equations, dies at 83 – Descended from a family of renowned physicists, he helped set the stage for the golden age of black hole astrophysics, reports Dennis Overbye for The New York Times. “This theory attributes what we call gravity to the curvature of spacetime by matter and energy. Its most mysterious and disturbing consequence was the possibility of black holes, places so dense that they became bottomless one-way exit ramps out of the universe, swallowing even light and time.I
Does the Universe spin? Ethan Siegel responds for Big Think. At all distances, the Universe extends along our line of sight. But we cannot measure lateral movements; can it rotate too?
NASA scientists will soon release an image of the universe that has never been seen before, showing some of the oldest stars and galaxies in the universe, reports Mint.com. “On July 12, NASA’s Goddard Space Flight Center in Maryland will host a live broadcast of photos and science data. Live coverage is available to the public via television and the NASA website.
The stunning perspectives show four of our galactic neighbors in a different light, NASA/JPL reports. New images using data from ESA (European Space Agency) and NASA missions show dust filling the space between stars in four of the closest galaxies to our own Milky Way. More than striking, the snapshots are also a scientific treasure, providing insight into how the density of dust clouds can vary widely within a galaxy.
The Webb Telescope will look for signs of life there –-The first question astronomers want to answer about exoplanets: do they have atmospheres conducive to life? reports Carl Zimmer for the New York Times. “Identifying an atmosphere in another solar system would be quite remarkable. But there is even a chance – albeit a tiny one – that one of these atmospheres offers what is called a biosignature: a signal of life itself.
Update – NASA’s CAPSTONE spacecraft is on its way to the moon. As part of its Artemis program to bring humans back to the Moon, NASA’s CAPSTONE spacecraft to map the orbit of the future Lunar Gateway space station has lifted off from New Zealand, reports New Scientist.
The big misconception of the Big Bang. Thanks to time-traveling telescopes, we can learn more about the Big Bang, reports Michelle Thaller in this great Big Think video:
“Information can escape from a black hole both outside and possibly into another universe” (Stephen Hawking’s Paradox), reports The Daily Galaxy. “It has been said that Newton gave us answers; Stephen Hawking asked us questions. A trio of physicists appear to be one step closer to solving the black hole’s information paradox, one of the most intriguing physical mysteries of our time.
Extraterrestrial life: What would constitute “irrefutable” proof? – Multiple sources of evidence – physical, chemical and biological – must converge for scientists to conclude that extraterrestrial life has been discovered, reports Big Think.
Laser scans reveal ancient cities hidden in the Amazon basinreports Big Think. The architecture and infrastructure uncovered required perhaps the greatest amount of skilled labor of any construction of the same period on the entire continent.
