NASA infrared imagery reveals wind shear displacing Marie’s strongest storms

NASA infrared imagery reveals wind shear displacing Marie's strongest storms
On Oct.5 at 6:20 a.m. EDT (1020 UTC), the MODIS instrument that flies aboard NASA’s Aqua satellite gathered infrared data on Marie that confirmed wind shear was adversely affecting the storm. Persistent westerly vertical wind shear showed strongest storms (yellow) pushed east of the center where cloud top temperatures were as cold as minus 50 degrees Fahrenheit (minus 45.5 Celsius).

NASA’s Aqua satellite provided an infrared view of Tropical Storm Marie that revealed the effects of outside winds battering the storm.


Wind shear occurs when winds at different levels of the atmosphere push against the rotating cylinder of winds, weakening the rotation by pushing it apart at different levels.

Infrared light is a tool used to analyze the strength of storms in tropical cyclones by providing temperature information about a system’s clouds. The strongest thunderstorms that reach highest into the

Bluefin tuna in focus as Japan seeks boost to catch limits

MITO, Japan (AP) — Countries involved in managing bluefin tuna fisheries are set to face-off over a Japanese proposal to raise its catch quotas for the fish, highly prized for sushi and sashimi.

At an online meeting that began Tuesday, Japan is seeking to raise its catch limits for both smaller and larger bluefin tuna by 20%.

A slight improvement in the spawning population for the fish has raised confidence that it can recover from decades of overfishing. But conservation experts worry that the capture of small fish used for farming bluefin tuna is may be putting the recovery of the species in peril.

The Western and Central Pacific Fisheries Commission includes more than two dozen countries that collaborate to manage fisheries on the high seas and curb illegal and unauthorized fishing and other activities that endanger highly migratory species such as the Pacific bluefin.

Countries participating in management of

ISS Astronauts Take Delivery of a Brand New Space Toilet

The International Space Station received its latest delivery of food, tools, and experiments on Monday. It also included a brand new space toilet.

The cargo arrived on the Cygnus spacecraft after launching the previous day aboard Northrop Grumman’s Antares rocket.

NASA astronaut Chris Cassidy and Russian cosmonaut Ivan Vagner used the space station’s robotic arm to assist in the docking procedure 261 miles (420 km) above the South Pacific Ocean, with the procedure finishing at around 8 a.m. ET.

Cygnus, which is also called SS Kalpana Chawla after the first astronaut of Indian origin launched to space but who sadly died in the 2003 Space Shuttle Columbia disaster, will stay docked at the ISS for the next three months.

Cassidy, Vagner, and the third space station inhabitant, Russian cosmonaut Anatoly Ivanishin, wasted no time in unloading Cygnus, with Cassidy tweeting his delight at receiving some fresh edibles from the team

Facebook to tap 1,200 rooftops to power Singapore data centre, operations

Facebook has inked a deal with Sunseap Group to tap solar energy that will power its data centre and operations in Singapore. Generated from solar panels to be placed atop 1,200 apartment blocks and 49 government buildings across the island, the power is estimated to reach 100 MegaWatt-peak (MWp) in capacity when fully completed in 2022.

Solar technology is one of the top picks for renewable energy sources in the future.


The agreement with local solar energy company Sunseap was touted to be the largest signed under a virtual power purchase agreement, according to a statement released Monday by Sunseap. Such agreements refer to contracts that outline a pre-agreed price at which the buyer will purchase a project’s renewable energy. This energy can be generated from a renewable energy project located away from a company’s premises, but co-located on the same grid.

NASA imagery reveals Tropical Storm Chan-hom’s skewed structure

NASA imagery reveals Tropical Storm Chan-hom's skewed structure
On Oct. 5, 2020, NASA’s Terra satellite provided a visible image of Tropical Storm Chan-hom several hundred miles northwest of Guam (lower right). Credit: NASA Worldview, Earth Observing System Data and Information System (EOSDIS).

NASA’s Terra satellite obtained visible imagery of Tropical Storm Chan-hom as it continued moving though the Northwestern Pacific Ocean. The imagery revealed that the center of circulation was exposed and its strongest storms were south of the center.


Tropical Depression 16W formed on Oct. 4 and strengthened into a tropical storm on Oct 5. Once it reached tropical storm strength, it was re-named Chan-hom. Laos submitted the name Chan-hom to the World Meteorological Organization list. The name is a type of tree in Laos.

Astronomers just spotted a planet floating freely in space without a star

  • Scientists have used gravitational lensing to detect a so-called ‘rogue planet’ that doesn’t orbit a star and floats freely in space.
  • The planet is relatively small, but researchers can’t tell for certain how far away it is from Earth.
  • It’s possible that the Milky Way is home to trillions of these free planets.

We think of our solar system as typical, or even “normal,” but in the universe, there’s really no such thing as normal. So many circumstances exist with regard to planets, stars, moons, and other objects that there’s no clear arrangement that the cosmos favors over any other, and there are even free-floating “rogue planets” that have escaped the systems they developed in and are just sort of doing their own thing.

Your ‘Most Convenient’ Meteor Shower Of 2020 Peaks This Week Near The Big Dipper

If you want to see “shooting stars” this week just look to the northern night sky right after dark.

This week sees the peak of the Draconid meteor shower, an annual event that sees around 10 “shooting stars” per hour appear in the night sky.

Like all meteor showers, it’s best seen in dark skies and requires patience, but while most such displays are best viewed after midnight, there’s something very different about the Draconids.

The one can be viewed right after dark. In fact, it’s going to be at its best right through the night—and there’s a reason for that.

Here’s everything you need to know about seeing “shooting stars” during this peaks Draconid meteor shower.

Mars will bright and beautiful in the October 2020 night sky.


NASA

Forget Halloween. This October is all about the glory of Mars, as the glimmering red planet puts on a show in the night sky. You can enjoy Mars as a bright point of light all month long, but there are two special dates to mark on your calendar: Oct. 6 when the planet makes a close approach to Earth, and Oct. 13, when it will be in opposition. 

Spotting Mars

Mars has a reputation as the “red” planet, but its color in the night sky is a little more on the Halloween side of the spectrum. It appears as a bright orange-red dot to the naked eye, like a little spot of glittering rust.

154-Foot NEO To Zoom Past Earth At 14,000 Km/hr

KEY POINTS

  • Asteroid 2020RR2 is set to pass by the Earth on Oct. 6, at 10:55 a.m. EDT
  • The NEO will be as tall as the Chicago Water Tower and half as tall as the Statue of Liberty
  • 2020RR2’s close approach will occur on the same day as Mars’ close approach to Earth

An asteroid about as tall as the Chicago Water Tower will zip past Earth this Tuesday, NASA’s Center for Near Earth Object Studies data reveals. 

Towering at a height of 154 feet, this Near-Earth Object (NEO) will make its approach on Oct. 6, at exactly 10:55 a.m. EDT. Named 2020RR2, it will fly by the planet at about 4.08 km/s or 14,000 km/hr. This NEO will be about half as tall as the Statue of Liberty in New York.

Along the course of its approach, 2020RR2 can get as close as 6 million kilometers from the planet’s
