For the First Time, Physicists Accelerated Light Beams in Curved Space in the Lab

Physicists have demonstrated accelerating light beams on flat surfaces, where acceleration has caused the beams to follow curved trajectories. However, a new experiment has pushed the boundaries of what’s possible to demonstrate in a lab. For the first time in an expeirment, physicists have demonstrated an accelerating light beam in curved space. Instead of traveling along a geodesic trajectory (the shortest path on a curved surface) it bends away from this trajectory due to the acceleration.

Scientists Take Viewers to the Center of the Milky Way

Scientists Take Viewers to the Center of the Milky Way

A new visualization provides an exceptional virtual trip — complete with a 360-degree view — to the center of our home galaxy, the Milky Way. This project, made using data from NASA's Chandra X-ray Observatory and other telescopes, allows viewers to control their own exploration of the fascinating environment of volatile massive stars and powerful gravity around the monster black hole that lies in the center of the Milky Way.

NASA Wants to Build a Magnetic Shield Around Mars

NASA Wants to Build a Magnetic Shield Around Mars

This week, NASA’s Planetary Science Division (PSD) hosted a community workshop at their headquarters in Washington, DC. Known as the “Planetary Science Vision 2050 Workshop“, this event ran from February 27th to March 1st, and saw scientists and researchers from all over the world descend on the capitol to attend panel discussions, presentations, and talks about the future of space exploration.

Huge sheets of ice found hidden just beneath the surface of Mars

Huge sheets of ice found hidden just beneath the surface of Mars

Its an established fact that Mars was once a warmer and wetter place, with liquid water covering much of its surface. But between 4.2 and 3.7 billion years ago, the planet lost its atmosphere, which caused most of its surface water to disappear. Today, much of that water remains hidden beneath the surface in the form of water ice, which is largely restricted to the polar regions.

Astronomers figure out how black holes can blast out relativistic jets of material across light years of space

Astronomers figure out how black holes can blast out relativistic jets of material across light years of space

Black holes have been an endless source of fascination ever since Einstein’s Theory of General Relativity predicted their existence. In the past 100 years, the study of black holes has advanced considerably, but the awe and mystery of these objects remains. For instance, scientists have noted that in some cases, black holes have massive jets of charged particles emanating from them that extend for millions of light years.

Multi-planet System Found Through Crowdsourcing

Multi-planet System Found Through Crowdsourcing

A system of at least five exoplanets has been discovered by citizen scientists through a project called Exoplanet Explorers, part of the online platform Zooniverse, using data from NASA's Kepler space telescope. This is the first multi-planet system discovered entirely through crowdsourcing. A study describing the system has been accepted for publication in The Astronomical Journal.

The ozone hole is definitely recovering

The ozone hole is definitely recovering

The ozone layer is a integral part of what makes Earth habitable. This region of the stratosphere is responsible for absorbing the majority of the Sun’s ultraviolet radiation, thus ensuring terrestrial organisms are not irradiated. Since the 1970s, scientists became aware of a steady decline in this layer around the southern polar region, along with and a major seasonal decrease. This latter phenomena, known as the “ozone hole”, has been a major concern for decades.

Explainer: ‘bomb cyclones’ – the intense winter storms that hit the US (and Australia too)

Explainer: ‘bomb cyclones’ – the intense winter storms that hit the US (and Australia too)

The eastern United States experienced a very severe winter storm last week, which caused damaging winds, heavy snow and the highest tide on record for Boston. Meteorologists call this type of storm a “bomb cyclone”, or simply a “bomb”. But what is it?

Quantum Computing Is Going to Change the World. Here’s What This Means for You.

Quantum Computing Is Going to Change the World. Here’s What This Means for You.

The science and tech world has been abuzz about quantum computers for years, but the devices are not yet affecting our daily lives. Quantum systems could seamlessly encrypt data, help us make sense of the huge amount of data we’ve already collected, and solve complex problems that even the most powerful supercomputers cannot – such as medical diagnostics and weather prediction.

These 5 tips may help you finally quit smoking

These 5 tips may help you finally quit smoking

Quitting smoking is a popular New Year’s resolution—but many have trouble sticking with it. “Many people underestimate how difficult it is to not only quit smoking, but to maintain the change,” says Zane Freeman, research coordinator for the YMCA exercise intervention for smoking cessation study taking place at the University of Texas at Austin.

Scientist at work: I’ve dived in hundreds of underwater caves hunting for new forms of life

Scientist at work: I’ve dived in hundreds of underwater caves hunting for new forms of life

Maybe when you picture a university professor doing research it involves test tubes and beakers, or perhaps poring over musty manuscripts in a dimly lit library, or maybe going out into the field to examine new crop-growing techniques or animal-breeding methods. All of it’s good, solid research and I commend them all.
