April 11 (UPI) — Scientists have struggled to define the upper limit of the cosmic optical background, the total amount of light produced by all of the galaxies in the universe. But new observations from NASA’s New Horizons spacecraft have allowed astronomers to place a ceiling on the measurement.

“Determining how much light comes from all the galaxies beyond our own Milky Way galaxy has been a stubborn challenge in observational astrophysics,” Michael Zemcov, an assistant professor of astrophysics at the Rochester Institute of Technology, said in a news release.

The reflection of the sunlight off interplanetary space dust makes the task of measuring the cosmic optical background from Earth quite difficult.

NASA will present new discoveries about the ocean worlds in our solar system on Thursday, the agency announced. Learning more about ocean worlds could help in the agency’s quest for life beyond Earth.

The findings were gathered by researchers through the Hubble Space Telescope and Cassini spacecraft. Cassini has been orbiting Saturn since 2004, and the mission ends this year.

“During its time at Saturn, Cassini has made numerous dramatic discoveries, including a global ocean that showed indications of hydrothermal activity within the icy moon Enceladus, and liquid methane seas on its moon Titan,” NASA said in a release.

Break out the censor’s black bars for naked singularities. Quantum effects could be obscuring these impossible predictions of general relativity, new calculations show.

Albert Einstein’s classical equations of general relativity do a fairly good job of describing gravity and space-time. But when it comes to the most extreme objects, such as black holes, general relativity runs into problems.
