Why the ‘Super Weird’ Moons of Mars Fascinate Scientists - The New York Times

Why the 'Super Weird' Moons of Mars Fascinate Scientists - The New York Times

Mars is the darling of many planetary scientists, who continue to visit it through increasingly advanced robotic explorers. But don't forget that our planetary neighbor is adorned with two moons: puny Phobos , a lumpy mass 17 miles across; and diminutive Deimos , just 9 miles long. Their names in ancient Greek may mean "fear" and "dread', but the aesthetics of these Lilliputian space potatoes inspire anything but.

They don't look anywhere near as interesting as the volcanic or icy-ocean moons of Jupiter and Saturn, nor is their desolation as extreme or diverse as Earth's moon. But that hasn't stopped generations of planetary scientists from being eager to get a closer look at the ramshackle duo.

Giant waves of sand are moving on Mars | Science | AAAS

Researchers have spotted large waves of martian sand migrating for the first time. The discovery dispels the long-held belief that these "megaripples" haven't moved since they formed hundreds of thousands of years ago. They're also evidence of stronger-than-expected winds on the Red Planet.

It's pretty staggering that humans can detect these changes on Mars, says Ralph Lorenz, a planetary scientist at the Johns Hopkins University Applied Physics Laboratory who was not involved in the research. "We can now measure processes on the surface of another planet that are just a couple times faster than our hair grows."

How Mars and the moon could become your next neighborhood

Mars and the moon could be the next out-of-this-world neighborhoods for Americans someday, possibly in the next 10 years.

A formal request for ideas went out Friday for what officials call a fission surface power system, The Associated Press reported . Energy officials and scientists from NASA and the Idaho National Laboratory, which conducts nuclear research, will evaluate the ideas and settle on a company to work with.

The government is breaking the project into two phases: developing a reactor design and then building two prototypes — one for testing and one to ship to the moon. The building phase also calls for designing a flight system and lander to transport the reactor.

How did a black hole suddenly turn itself off and on again?

How did a black hole suddenly turn itself off and on again?

Can a black hole really flip a switch on itself? At least one did, since it was caught doing just that in real time.

Phenomena like this just don't happen. That explains the shock a team of MIT astronomers got when they observed a flash of brightness from a supermassive black hole that then dimmed as if someone pulled the plug on it. Then, as if out of nowhere, it restarted like all your electrical appliances after a thunderstorm blackout.

"We expect that luminosity changes this big should vary on timescales of many thousands to millions of years," said Erin Kara , assistant professor of physics at MIT, in a press release . "But in this object, we saw it change by [a factor of] 10,000 over a year, and it even changed by a factor of 100 in eight hours, which is just totally unheard of and really mind-boggling."

How a Black-Hole Collision Created a Spark of Light - The Atlantic

But black holes don't emit light; they trap it. Entire stars can become shredded and swallowed during an unlucky encounter with a black hole. How could any encounter between two black holes produce the kind of light our eyes can see?

The disk is home to smaller black holes, and sometimes they get close enough to collide. The researchers behind the new paper, published today in Physical Review Letters , believe that when two of these black holes smashed together, the force of the impact warped the space around them and sent gravitational waves rippling outward, like rings in a pond. The black holes merged into a single, larger black hole and shot through the disk of gas, jostling nearby matter and heating it up.

Black hole breakthrough as 'millions could be hiding in plain sight' | Science | News |

But, earlier this year, astronomers spotted a black hole about 1,011 light-years from our Solar System in the star system HR 6819 and it could be the closest to Earth.

Unveiled in the journal Astronomy & Astrophysics, the invisible object is locked in an orbit with two visible stars and is estimated to be about four times the mass of the Sun and roughly 2,500 light-years closer than the next black hole.

Kareem El-Badry, a PhD student at the University of California, Berkeley, who specialises in binary star systems told National Geographic: “It seems like it’s been hiding in plain sight.

Cases of black hole mistaken identity

Supermassive black holes grow by pulling in surrounding material, which is heated and produces radiation at a wide range of wavelengths including X-rays. Many astronomers think this growth includes a phase, which happened billions of years ago, when a dense cocoon of dust and gas covers most black holes. These cocoons of material are the fuel source that enables the black hole to grow and generate radiation.

Based on the current picture held by astronomers many black holes immersed in such a cocoon (referred to as "heavily obscured" black holes) should exist. However, this type of growing black hole is notoriously difficult to find, and until now the observed number has fallen short of predictions—even in the deepest images like the CDF-S.

A Black Hole Popping Out of a Traversable Wormhole Should Give Off a Very Specific Signal in

Gravitational wave astronomy has changed the way we view the cosmos. In only a few years we have observed the collisions of black holes and neutron stars, confirming our theoretical understanding of these strange objects. But as gravitational wave astronomy matures, it will allow us to probe the very nature of space and time itself. While that day is a long way off, it hasn’t stopped the theory folks from dreaming up new discoveries.

Wormholes, on the other hand, are entirely hypothetical. In theory, they are similar to black holes, but rather than a simple hole in space, wormholes would connect one region of space to another. Perhaps they could even connect different universes. They have long been studied by theoretical physicists as a way to test the limits of general relativity.

The Moon is an Ideal Spot for a Gravitational Wave Observatory - Universe Today

In the coming years, multiple space agencies will be sending missions (including astronauts) to the Moon’s southern polar region to conduct vital research. In addition to scouting resources in the area (in preparation for the construction of a lunar base) these missions will also investigate the possibility of conducting various scientific investigations on the far side of the Moon.

However, two prominent scientists (Dr. Karan Jani and Prof. Abraham Loeb) recently published a paper where they argue that another kind of astronomy could be conducted on the far side of the Moon – Gravitational Wave astronomy! As part of NASA’s Project Artemis , they explain how a Gravitational-wave Lunar Observatory for Cosmology (GLOC) would be ideal for exploring GW in the richest and most challenging frequencies.

Ever wondered why you can see the moon sometimes during the day? - The Washington Post

Kids are often taught to associate the sun with the day and the moon and stars with the night. Yet why does the moon sometimes come out during the daylight hours?

The answer is somewhat simple: The moon and stars are always somewhere in the sky, but we can't always see them.

"The sun is so bright during the day that it kind of drowns out the light from the moon and the stars," says astrophysicist Cheyenne Polius. She is president and co-founder of the Saint Lucia National Astronomy Association in the Caribbean region.

It's often repeated how most of the cameras that landed on the moon stayed on the moon. Astronaut Gene Cernan had been telling the story of how he left his camera on the lunar rover for years, recounting the tale in interviews.

It's easy to accept Cernan at his word – he's an American hero who flew to space three times, twice to the moon – so as far as everyone was concerned, including the press, the camera was right where he said he left it. Plus, a quick scan of the Apollo 17 stowage list reveals no mention of a lunar surface camera splashing down with the command module. So why the mystery?

Experts Say Near Earth Asteroid Due To Come Within 300 Miles Of Earth In November Not A Concern

CBS Detroit – There’s a video on Youtube saying we are about to have another “very-close encounter” with an asteroid. What the Jet Propulsion Lab in California calls “Near-Earth-Objects” or NEOs. Now keep in mind asteroids have been coming close or have hit our planet for millions of years, and many do daily.

However, one Youtube video says an asteroid called “ 2018 VP1 “, which is about 6 feet diameter will pass within about 300 miles of our planet on November 2, 2020. However, some experts are saying this nothing to fear. First off there’s the math, asteroid “2018 VP1” is projected to come 0.02 times the distance between the earth and the moon. Given that the moon is 239,000 miles away, 0.02 equates to 4,780 miles. Now your thinking that’s far off right?

One way to make a personal contribution to energy change is to generate electricity from solar energy using a mini PV system (PV, Photo Voltaic). These are often referred to as balcony power plants. They supply electricity from sunlight to use it for their own purposes free of charge. The electrical consumers such as refrigerators, devices in standby etc. are then completely or partially operated with the self-generated electricity.

More recently, they have been detected through photometric transits from space, and through far-IR/mm gas emission within debris disks.

Scientists identify asteroids of interstellar origin moving in our Solar System- Technology News,

Scientists at São Paulo State University's Institute of Geosciences and Exact Sciences (IGCE-UNESP) in Rio Claro, Brazil, have recently spotted 19 asteroids of interstellar origin. These asteroids are classified as Centaurs, which are outer Solar System objects that revolve around the Sun in the region between the orbits of Jupiter and Neptune.

The study titled An interstellar origin for high-inclination Centaurs was supported by FAPESP and has been published in the Royal Astronomical Society's Monthly Notices.

Scientists rediscover 'lost planet' more like the ones in our own solar system - CNET

The NGTS facility in Chile is working on tracking down exoplanets located in their stars' "Goldilocks" zones.

Exoplanets, those mysterious planets that dwell outside of our solar system, are always fascinating, but humanity is particularly interested in those located in their stars' habitable zones where liquid water might exist. A new method for detecting exoplanets could help scientists spot many more of these intriguing, distant worlds.

This is a cosmic detective story. TESS first located the planet by seeing a subtle dip in brightness when it crossed in front of its star. But TESS only stares at a section of space for a limited period of time, usually 27 days. Scientists like to observe two dips in brightness to confirm an exoplanet's existence, but some of those planets take longer than 27 days to circle back around.

At the heart of understanding our space environment is the knowledge that conditions throughout space — from the Sun to the atmospheres of planets to the radiation environment in deep space — are connected.

Studying this connection — a field of science called heliophysics — is a complex task: Researchers track sudden eruptions of material, radiation, and particles against the background of the ubiquitous outflow of solar material.
