The University of Arizona's Steward Observatory has partnered with the Catalina Sky Survey, which searches for near-Earth asteroids from atop Mount Lemmon, in an effort dubbed Searches after Gravitational Waves Using ARizona Observatories, or SAGUARO, to find optical counterparts to massive mergers. "Catalina Sky Survey has all of this infrastructure

Thousands of planets have been discovered by NASA's Kepler space telescope.

Thanks to coordinated observations of the planet in January 2017 by six ground-based optical and radio telescopes and NASA's Hubble Space Telescope, a University of California, Berkeley, astronomer and her colleagues have been able to track the effects of these storms -- visible as bright plumes above the planet's ammonia

Gamma-ray observations are not sensitive enough to clearly see the shape of the Moon's disk or any surface features.

Astronomers from Rice University and China's Sun Yat-sen University say their head-on impact scenario can explain Juno's previously puzzling gravitational readings, which suggest that Jupiter's core is less dense and more extended that expected. "This is puzzling," said Rice astronomer and study co-author Andrea Isella. "It suggests that something happened

"We are all excited about the decision that moves the Europa Clipper mission one key step closer to unlocking the mysteries of this ocean world," said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. "We are building upon the scientific insights received from the

Physicists at Durham University, UK, simulated the cosmos using an alternative model for gravity -- f(R)-gravity, a so called Chameleon Theory..

The conundrum is that the disk shouldn't be there, based on current astronomical theories.
