Vanderbilt astrophysicist Karan Jani has led a series of studies that make the first case for a gravitational wave infrastructure on the surface of the moon. The experiment, dubbed Gravitational-Wave Lunar Observatory for Cosmology, uses the moon's environment and geocentric orbit to analyze mergers of black holes, neuron stars and dark matter candidates within almost 70 percent of the entire observable volume of the universe, he said.

"By tapping into the natural conditions on the moon, we showed that one of the most challenging spectrum of gravitational waves can be measured better from the lunar surface, which so far seems impossible from Earth or space," Jani said.

"The moon offers an ideal backdrop for the ultimate gravitational wave observatory, since it lacks an atmosphere and noticeable seismic noise, which we must mitigate at great cost for laser interferometers on Earth," said Avi Loeb, professor of science at Harvard University and bestselling author of books about black holes, the first stars, the search for extraterrestrial life and the future of the universe.

Little is known about Venus weather at night, as the absence of sunlight makes imaging difficult. Now, researchers have devised a way to use infrared sensors on board the Venus orbiter Akatsuki to reveal the first details of the nighttime weather of our nearest neighbor. Their analytical methods could be used to study other planets including Mars and gas giants as well. Furthermore, the study of Venusian weather granted by their methods could allow researchers to learn more about the mechanisms underpinning Earth's weather systems.

Durham, Toronto and Princeton Universities have teamed up with NASA and the Canadian Space Agency to build a new kind of astronomical telescope. SuperBIT flies above 99.5% of the Earth's atmosphere, carried by a helium balloon the size of a football stadium. The telescope will make its operational debut next April and when deployed should obtain high-resolution images rivaling those of the Hubble Space Telescope. Mohamed Shaaban, a Ph.D. student at the University of Toronto, will describe SuperBIT in his talk today (Wednesday 21 July) at the online RAS National Astronomy Meeting (NAM 2021).

Light from a distant galaxy can travel for billions of years to reach our telescopes. In the final fraction of a second, the light has to pass through the Earth's swirling, turbulent atmosphere. Our view of the universe becomes blurred.
