'Ring of Fire' Solar Eclipse Thrills Skywatchers Around the World (and in Space, Too!) | Space

The moon crossed the face of the in a dazzling "ring of fire" solar eclipse today (Dec. 26) to the delight of potentially millions of spectators around the world in the Eastern Hemisphere. Even astronauts in space marveled at the view. 

The eclipse, known as an annular solar eclipse, began in Saudi Arabia, with the moon passing in front of the sun, but not completely covering the star's face. Instead, it left a brilliant ring, or annulus, that gave it a "ring of fire" effect. It was the last solar eclipse of 2019 , indeed, of the decade.

See Venus and the Moon Shine Together in Post-Christmas Gift (Earthshine, Too!) | Space

The planet Venus continues to shine like a silvery-white lantern in the southwestern sky for about 2.5 hours after sundown. On Saturday evening (Dec. 28), a lovely crescent moon will join Venus in the twilight sky, making for an eye-catching post-Christmas celestial ornament.  

Although by the standards of most Venus-moon pairings they will not be unusually close together, they still will likely draw the attention of even those who normally do not look up.  Venus will appear to hover about 2.5 degrees almost directly above and ever-so-slightly to the left of the moon.

Launch of China Heavy Rocket a success; Continues its Roadmap to Moon & Beyond | Tech Times

China's launch of its Long March 5 rocket was successful. This rocket was the country's homegrown design that could ultimately be tasked with taking the astronauts of China to the Moon, Mars, and even beyond. While there are only a few numbers of flights of this rocket to its name, it has not stopped the Chinese space agency from creating an ambitious roadmap for its beyond-Earth activities.

Also called the Changzheng 5, ZM-5, and LM-5, the Long March 5 Rocket  was made for 55,000-pound payloads that make it roughly similar to the Delta IV Heavy Rocket which was used in the United States. The 4-booster design of the rocket uses, as indicated in a slashgear.com article, "non-hypergolic liquid rocket propellants, for a total of 2,200,000 pounds of thrust."

Asteroid warning: Catastrophic reality of horror object smashing into Earth REVEALED | Science |

An asteroid smashing into Earth's surface presents one of the most serious threats to the planet. There is evidence the planet has repeatedly been struck by asteroids in the past - with the largest observed crater formed in South Africa, estimated to have hit around two billion years ago.

But, writing in ‘What Does Rain Smell Like?’, meteorologists Simon King and Clare Nasir explain the horrific impacts of an asteroid smashing into the planet now.

Will This Approaching Asteroid Hit Earth Or Explode In The Atmosphere?

NASA has spotted an asteroid that's expected to approach the planet tomorrow. Given the size and speed of the incoming asteroid, there's a chance it might cause a huge explosion in the atmosphere if it hits Earth.

The approaching asteroid has been identified by NASA's Center for Near-Earth Object Studies (CNEOS) as 2019 YX2 . According to CNEOS, this asteroid is currently flying towards Earth at a speed of almost 12,400 miles per hour. The agency estimated that the asteroid has a diameter of around 105 feet.

A 426-Foot-Wide Asteroid Will Zoom Past Earth Tomorrow At Nearly 54,000 MPH

A large, pyramid-sized asteroid is making its way towards Earth and will swing by for a close approach tomorrow, NASA has announced.

Interestingly enough, tomorrow’s flyby will be the closest encounter with Earth in the last 11 years for 2019 XF. According to a report released earlier today by NASA’s Jet Propulsion Laboratory (JPL), the object often passes by Earth as it orbits the sun once every 573 days, or a little over a year-and-a-half. The large asteroid also swings by Venus and Mercury as it treks the inner solar system, making frequent flybys of the three planets.

How 2019's space missions explored distant worlds | Science News

From asteroids to exoplanets, spacecraft are leaving no space rock unturned. While agencies in China, India and Israel made headlines with missions to the moon , here are some other places that space probes scouted in 2019.

NASA's Transiting Exoplanet Survey Satellite, or TESS, racked up eight exoplanet finds in its first few months of observation ( SN: 2/2/19, p. 12 ). That initial cache included some weirdos, such as a planet that is about as dense as pure water and a "lava world" known as LHS 3844b that sizzles at about 540° Celsius.

Earth was stressed before dinosaur extinction: Fossilized seashells show signs of global warming,

New evidence gleaned from Antarctic seashells confirms that Earth was already unstable before the asteroid impact that wiped out the dinosaurs.

The study, led by researchers at Northwestern University, is the first to measure the calcium isotope composition of fossilized clam and snail shells, which date back to the Cretaceous-Paleogene mass extinction event. The researchers found that -- in the run-up to the extinction event -- the shells' chemistry shifted in response to a surge of carbon in the oceans.

Seismic Sensors in Orbit - Eos

Imagine it's 3:00 a.m. along the Pacific Northwest coast—it's dark outside and most people are asleep indoors rather than alert and going about their day. Suddenly, multiple seismometers along the coast of Washington state are triggered as seismic waves emanate from a seconds-old earthquake. These initial detections are followed rapidly by subsequent triggering of a dozen more instruments spread out both to the north, toward Seattle, and to the south, toward Portland, Ore.

Within a few seconds of the seismometers being triggered, computers running long-practiced seismic location and magnitude algorithms estimate the source of the shaking: a magnitude 7.0 earthquake 60 kilometers off the Washington coast at a depth roughly consistent with the Cascadia Subduction Zone (CSZ) interface, along which one tectonic plate scrapes—and occasionally lurches—past another as it descends toward Earth's interior.

These Star Wars-Style Lasers Could Track Space Junk In Earth's Orbit To Prevent Deadly Collisions

The Earth's orbit is cluttered with millions of pieces of space junk whizzing around the planet at 20,000 miles per hour. Reportedly , more than 400 satellites were launched in 2014 alone. Needless to mention, the sudden burst in the number fueled by companies like SpaceX, Boeing and Airbus have plans to deploy thousands of communications satellites into Earth-encircling orbits over the next few years.

Keeping track of all the satellites orbiting 38,000 kilometres above our heads is a NASA priority. However, a new system based on the neural network has provided a better way to keep track of these hazardous objects with telescopes. Researchers at the Chinese Academy of Surveying and Mapping have reportedly developed a new laser tracking system that can detect debris as small as three feet wide, improving on the current methods by around 1,500 times.

Understanding Distant Dust In Other Solar Systems Is Key To Imaging Exo-Earths, Says NASA

This image beautifully captures the zodiacal light, a triangular glow seen best in night skies free ... [+] of overpowering moonlight and light pollution. The photograph was taken at ESO's La Silla Observatory in Chile in September 2009, facing west some minutes after the Sun had set. A sea of clouds has settled in the valley below La Silla, which sits at an altitude of 2400 metres, with lesser peaks and ridges poking through the mist

A film of fine dust in our own solar system and in solar systems like ours has long been thought to be a potential bugaboo in imaging extrasolar earthlike planets, say astronomers. But planetary scientists are still not sure about the size, shape and scope of our own zodiacal cloud (made up of dust particles shed from comets and asteroids in orbit around the Sun). And they are hardly certain how to characterize such clouds of dust around far-flung planetary systems.

2010s Decade in Space Exploration - Most Powerful Space Moments

It's been an incredible decade for our solar system and beyond. Humanity has stretched its tendrils farther out into space than ever before. We explored asteroids, comets, new moons of Saturn, and the surface of Mars. Scientists detected gravitational waves and—in an incredible feat of technology and innovation—we recycled a rocket for the first time, ushering in a new era of exploration.

The decade started out with the retirement of a spaceflight workhorse (adios, space shuttles!) and ended with the announcement of an exciting new mission back to the moon (hello, Artemis!). Here, Popular Mechanics looks back at the most powerful moments in space and astronomy of the 2010s. It'll be a thrill to see what happens in the next decade.

Massive gas disk raises questions about planet formation theory

Recent advances in radio telescopes have yielded a surprise in this field. Astronomers have found that several debris disk still possess some amount of gas. If the gas remains long in the debris disks, planetary seeds may have enough time and material to evolve to giant planets like Jupiter. Therefore, the gas in a debris disk affects the composition of the resultant planetary system.

"We found atomic carbon gas in the debris disk around 49 Ceti by using more than 100 hours of observations on the ASTE telescope," says Aya Higuchi, an astronomer at the National Astronomical Observatory of Japan (NAOJ). ASTE is a 10-m diameter radio telescope in Chile operated by NAOJ. "As a natural extension, we used ALMA to obtain a more detailed view, and that gave us the second surprise. The carbon gas around 49 Ceti turned out to be 10 times more abundant than our previous estimation.
