Future spaceships could use black holes as powerful launch pads to explore the stars.

A new study envisions firing laser beams that would curve around a black hole and come back with added energy to help propel a spacecraft to near the speed of light. Astronomers could look for signs that alien civilizations are using such a “halo drive,” as the study dubs it, by seeing if pairs of black holes are merging more often than expected.

Study author David Kipping, an astrophysicist at Columbia University in New York, came up with the idea of the halo drive through what he calls “the gamer’s mindset.”

A gravitational wave generating device comprising an energizing means such as magnetrons, which act upon energizable elements such as film bulk acoustic resonators or FBARs. A computer that controls the magnetrons’ phase. A gravitational wave generation device that exhibits directivity and forms a gravitational-wave beam. The utilization of a medium in which the gravitational wave speed is reduced in order to effect refraction of the gravitational wave and be a gravitational wave lens. A gravitational wave generator device that can be directed in order to propel an object by its momentum or by changing the gravitational field nearby the object to urge it in a preferred direction and be a propulsion means.

Adding to the largest astronomical data set ever assembled online, the Pan-STARRS telescope has posted 1.6 petabytes of data.

Future neutrino experiments may provide tomographic scans of Earth’s interior by viewing solar neutrinos that pass through our planet’s layers.

The Sun showers Earth with neutrinos, but this “glow” doesn’t dim when the Sun goes down. At night, solar neutrinos penetrate Earth, impinging detectors from below. Like x rays in a medical scanner, these planet-traversing neutrinos might offer information about the material they pass through. New theoretical calculations show that future experiments, such as the Deep Underground Neutrino Experiment (DUNE), could characterize the different layers inside Earth with neutrino-based tomography.

Call it the “Little Bog of Horrors.” In what is believed to be a first for North America, biologists at the University of Guelph have discovered that meat-eating pitcher plants in Ontario’s Algonquin Park wetlands consume not just bugs but also young salamanders.

Design for system that provides solar- or wind-generated power on demand should be cheaper than other leading options.

The drone is adapted from a robot that killed off coral’s predators.

The NGC1052-DF2 ultra-diffuse galaxy was first discovered and presented as the ‘galaxy without dark matter’. Astronomers from Spain found new evidence disputing the previous estimates of the galaxy’s mass and distance.
