Heat energy leaps through empty space, thanks to quantum weirdness

If you use a vacuum-insulated thermos to help keep your coffee hot, you may know it's a good insulator because heat energy has a hard time moving through empty space. Vibrations of atoms or molecules, which carry thermal energy, simply can't travel if there are no atoms or molecules around.

Scientists develop molecular sensor that can emit light in more colours than ever before

Physicists at the University of Alberta have created a molecular colourant that can emit light in a wider range of colours than any other molecule currently available.

Cheers! Maxwell's electromagnetism extended to smaller scales

On Dec. 11, 2019, a general framework for incorporating and correcting for nonclassical electromagnetic phenomena in nanoscale systems will be presented in the journal Nature.

Multiplication and division of the orbital angular momentum of light

Optical beams carrying orbital angular momentum (OAM) have attracted growing attention during the last decades, exhibiting disruptive applications in a wide range of fields: particle trapping and tweezing, high-resolution microscopy, astronomical coronagraphy, high-capacity telecommunication and security.

Astronomy & Space news

Water common—yet scarce—in exoplanets

The most extensive survey of atmospheric chemical compositions of exoplanets to date has revealed trends that challenge current theories of planet formation and has implications for the search for water in the solar system and beyond.

Relativistic jet of the blazar S5 0836+710 investigated in detail

Using very long baseline interferometry (VLBI), astronomers have performed comprehensive multiwavelength observations of the radio emission in the blazar S5 0836+710. The new research, presented in a paper published December 2 on arXiv.org, reveals important insights about the structure the blazar's relativistic jet.

ALMA spots most distant dusty galaxy hidden in plain sight

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted the light of a massive galaxy seen only 970 million years after the Big Bang. This galaxy, called MAMBO-9, is the most distant dusty star-forming galaxy that has ever been observed without the help of a gravitational lens.

Two rovers to roll on Mars again: Curiosity and Mars 2020

Curiosity won't be NASA's only active Mars rover for much longer. Next summer, Mars 2020 will be headed for the Red Planet. While the newest rover borrows from Curiosity's design, they aren't twins: Built and managed by NASA's Jet Propulsion Laboratory in Pasadena, California, each has its own role in the ongoing exploration of Mars and the search for ancient life. Here's a closer look at what sets the siblings apart.

Second stellar population found in Milky Way's thick disk

A new study on the kinematics and chemical composition of a sample of stars in the vicinity of the sun, led by Dr. Daniela Carollo, researcher of the Italian National Institute for Astrophysics, has revealed that the stars that make up the thick disk of the Milky Way belong to two distinct stellar populations with different characteristics and not to a single one, as has been thought for more than two decades.

NASA's treasure map for water ice on Mars

NASA has big plans for returning astronauts to the Moon in 2024, a stepping stone on the path to sending humans to Mars. But where should the first people on the Red Planet land?

A new way to measure cosmic black holes

Supermassive black holes are the largest black holes, with masses that can exceed a billion Suns. Just this spring, the first-ever image of the supermassive black hole at the center of the Messier 87 galaxy was taken, and researchers recently spotted the largest supermassive black hole ever seen. Despite these groundbreaking efforts, figuring out how these black holes drive a galaxy's shape and structure continues to be a challenge because most of them are too far away for current telescopes to resolve accurately.

Engineers pull off daring rescue of OSIRIS-REx asteroid mission

On Friday, Oct. 11, the OSIRIS-REx team should have been preparing to point their spacecraft cameras precisely over the asteroid Bennu to capture high-resolution images of a region known as Osprey. It is one of four sites scientists are considering from which the spacecraft can safely collect a sample in late 2020.

Jeff Bezos's Blue Origin rocket makes 12th test flight

Blue Origin, the space company owned by Amazon CEO Jeff Bezos, launched the 12th crewless test of its New Shepard rocket on Wednesday, pushing the first flights with passengers to 2020.

Revealing the physics of the Sun with Parker Solar Probe

Nearly a year and a half into its mission, Parker Solar Probe has returned gigabytes of data on the Sun and its atmosphere. Following the release of the very first science from the mission, five researchers presented additional new findings from Parker Solar Probe at the fall meeting of the American Geophysical Union on Dec. 11, 2019. Research from these teams hints at the processes behind both the Sun's continual outflow of material—the solar wind—and more infrequent solar storms that can disrupt technology and endanger astronauts, along with new insight into space dust that creates the Geminids meteor shower.

X-ray satellite XMM-Newton celebrates 20 years in space

Two decades ago, on Dec. 10, 1999, an Ariane 5 rocket climbed into the morning sky from Kourou, French Guiana. It carried into orbit the X-ray Multi-Mirror Mission (XMM-Newton), the largest scientific spacecraft yet built by ESA (European Space Agency) and a pioneering satellite for studying the universe with different kinds of light. XMM-Newton has studied over half a million X-ray sources, including supernovae, star-shredding black holes and superdense neutron stars.

Refueling satellites in space with the help of a robot

Many technologies that are essential for daily life—from communications to GPS navigation to weather forecasting—rely on the thousands of satellites that are orbiting Earth. When those satellites run out of gas and stop working, there's not much that can currently be done to fix them.

New NASA ebook reveals insights of Earth seen at night from space

Earth has many stories to tell, even in the dark of night. Earth at Night, NASA's new 200-page ebook, is now available online and includes more than 150 images of our planet in darkness as captured from space by Earth-observing satellites and astronauts on the International Space Station over the past 25 years.

Punching holes in opaque solar cells turns them transparent

Researchers in Korea have found an effective and inexpensive strategy to transform solar cells from opaque to transparent. Existing transparent solar cells tend to have a reddish hue and lower efficiency, but by punching holes that are around 100 μm in diameter (comparable in size to a human hair) on crystalline silicon wafers, it allows light through without coloring. The holes are then strategically spaced, so the human eye is unable to "see" the pattern. The work appears December 11 in the journal Joule.

This object-recognition dataset stumped the world's best computer vision models

Computer vision models have learned to identify objects in photos so accurately that some can outperform humans on some datasets. But when those same object detectors are turned loose in the real world, their performance noticeably drops, creating reliability concerns for self-driving cars and other safety-critical systems that use machine vision.
