A new study warns that astronomers measuring the rotation of distant exoplanets may often be measuring atmospheric winds instead, since the clouds of Venus circle the planet roughly 60 times faster than Venus itself actually spins. Kane proposes using multi-wavelength observations to correct for this, work that will matter enormously once the European Space Agency's PLATO mission launches in 2027 and, researchers predict, discovers several hundred Venus like exoplanets.
New research shows that extreme space weather can significantly raise radiation exposure on commercial flights and increase electronic faults in aircraft systems. A severe 1956 scale solar storm could expose passengers to a year's worth of radiation in a single flight, and the researchers point to last year's Airbus A320 grounding, triggered by a solar radiation linked flight computer fault, as proof this isn't theoretical. To address the gap, the team has proposed a new aviation specific radiation scale designed to give airlines clearer, more reliable guidance on when to monitor, reroute, or ground flights during severe events.
A new composite image combining data from Chandra, Hubble, Webb and the retired Spitzer telescope has helped astronomers solve a long standing puzzle in the Tarantula Nebula, a star forming region 160,000 light years away. Young, massive stars there should be heating enough gas to emit X-rays, but observations showed far less X-ray emission than predicted.
Largest Italian radio telescope located on an out of the way mountain plateau in southern Sardinia sheds light on the cosmos’ still misunderstood Fast Radio Bursts (FRBs).
Astronomers working with the JWST have found a galaxy only 1.3 billion years after the Big Bang that contains three black holes. Two are close to the galaxy's center and will merge soon. The third is more distant, and is expected to merge much later. The discovery shows that black hole mergers were an important contributor to the masses of the SMBH we find in galaxies today.
Scientists have discovered a rare star formation hidden in a distant galaxy, unlike anything seen before beyond the Milky Way. What’s more, the discovery offers a brand new way to measure the distribution of dark matter in distant galaxies.
What does a home actually need to do for us, beyond keeping the weather out? Engineers at MIT have started mapping the answer for astronauts heading to the Moon and Mars, tracing exactly how the walls, layouts and lighting around a person shape their stress, their loneliness and their sense of belonging. It turns out the science of surviving a place and the science of living in one are not the same thing at all, and I have spent enough of the last year thinking about that difference to know how much it matters.
