Cassini Finds Saturn Moon Has 'Sea Level' Like Earth

Cassini Finds Saturn Moon Has 'Sea Level' Like Earth

Saturn’s moon Titan may be nearly a billion miles away from Earth, but a recently published paper based on data from NASA’s Cassini spacecraft reveals a new way this distant world and our own are eerily similar. Just as the surface of oceans on Earth lies at an average elevation that we call “sea level,” Titan’s seas also lie at an average elevation.

Odd Behaviour of Star Reveals Lonely Black Hole Hiding in Giant Star Cluster

Odd Behaviour of Star Reveals Lonely Black Hole Hiding in Giant Star Cluster

Astronomers using ESO’s MUSE instrument on the Very Large Telescope in Chile have discovered a star in the cluster NGC 3201 that is behaving very strangely. It appears to be orbiting an invisible black hole with about four times the mass of the Sun — the first such inactive stellar-mass black hole found in a globular cluster and the first found by directly detecting its gravitational pull. This important discovery impacts on our understanding of the formation of these star clusters, black holes, and the origins of gravitational wave events.

Turning heat into electricity - Study finds topological materials could boost the efficiency of thermoelectric devices.

What if you could run your air conditioner not on conventional electricity, but on the sun’s heat during a warm summer’s day? With advancements in thermoelectric technology, this sustainable solution might one day become a reality.

Hubble Weighs in on Mass of Three Million Billion Suns

Hubble Weighs in on Mass of Three Million Billion Suns

In 2014, astronomers using the NASA/ESA Hubble Space Telescope found that this enormous galaxy cluster contains the mass of a staggering three million billion suns — so it’s little wonder that it has earned the nickname of “El Gordo” (“the Fat One” in Spanish)! Known officially as ACT-CLJ0102-4915, it is the largest, hottest, and brightest X-ray galaxy cluster ever discovered in the distant Universe.

Asteroid mining is getting closer to reality. Planetary resources Arkyd-6 satellite just launched

In 2009, Arkyd Aeronautics was formed with the intention of becoming the first commercial deep-space exploration program. In 2012, the company was renamed Planetary Resources, and began exploring the ambitious idea of asteroid prospecting and mining. By harnessing Near-Earth Objects (NEOs) for their water and minerals, the company hopes to substantially reduce the costs of space exploration.

How we created a mini ‘gamma ray burst’ in the lab for the first time

How we created a mini ‘gamma ray burst’ in the lab for the first time

Gamma ray bursts, intense explosions of light, are the brightest events ever observed in the universe – lasting no longer than seconds or minutes. Some are so luminous that they can be observed with the naked eye, such as the burst “GRB 080319B” discovered by NASA’s Swift GRB Explorer mission on March 19, 2008.

Lava tube openings found near the moon’s north pole

Lava tube openings found near the moon’s north pole

Between NASA, the Chinese National Space Agency, the European Space Agency and Roscosmos, there’s no shortage of plans for returning to the Moon and creating a permanent base there. Naturally, these plans have given rise to questions of where such bases should be built. So far, the top contenders have been lava tubes that have been spotted in various locations across the surface of the Moon and in the polar regions.

China has a plan to clean up space junk with lasers

China has a plan to clean up space junk with lasers

Orbital debris (aka. space junk) is one of the greatest problems facing space agencies today. After sixty years of sending rockets, boosters and satellites into space, the situation in the Low Earth Orbit (LEO) has become rather crowded. Given how fast debris in orbit can travel, even the tiniest bits of junk can pose a major threat to the International Space Station and threaten still-active satellites.

Everything you never wanted to know about bed bugs, and more

Everything you never wanted to know about bed bugs, and more

If some insects could save the world, others do their best to seriously complicate life on Earth. Among them the prize perhaps goes to the bed bug, which after decades of absence has returned to our homes, hotels and public facilities to seriously disturb us.

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

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.
