Artist’s impression of a microlensing event caused by a black hole observed from Earth towards the Large Magellanic Cloud. The light from a background star in the GMC is diffracted by a putative primordial black hole (lens) in the Milky Way’s halo and magnified when observed from Earth. Microlensing produces very characteristic variations in the … Read more
Enlarge / Ligeia Mare, the second largest amount of liquid hydrocarbons on Titan. During its T85 Titan flight on July 24, 2012, the Cassini spacecraft recorded an unexpectedly bright reflection on the surface of Lake Kivu Lacus. The Visual and Infrared Mapping Spectrometer (VIMS) data was interpreted as a roughness on the methane-ethane lake, which … Read more
Will future humans use warp drives to explore the cosmos? We are not in a position to rule out this possibility. But if our distant descendants ever do, that will not be the case dilithium crystals, and Scottish accents will have evaporated into history by then. Warp drives have their roots in one of the … Read more
A geoengineering technique designed to lower high temperatures in California could inadvertently intensify heat waves in Europe, according to a study modeling the unintended consequences of regional tinkering with a changing climate. The article shows that targeted interventions to reduce temperatures in a given area for one season may provide temporary benefits for some population … Read more
The roar of the surf could be the soundtrack to Saturn’s moon Titan. New analysis shows that the vast amounts of liquid methane and ethane wrapping around Titan’s surface are likely populated by waves that erode the coastline and carve the shapes of the vast rivers and lakes native to the exotic, hazy moon. This … Read more

Will future humans use warp drives to explore the cosmos? We are not in a position to rule out this possibility. But if our distant descendants ever do, it won’t involve dilithium crystals, and the Scottish accents will have faded into history by then.

Teflon objects (orange cylinders) were placed in a waveguide with a rectangular cross-section. Then, an electromagnetic signal (blue wavefront) was injected from the right to obtain information about the metal cube, shown in gray. By measuring the wave field in … Read more
