Survey of the sky pushes the boundaries of what we know about the structure of our galaxy — ScienceDaily

Scientists from Cardiff University have helped produce a brand-new, three-dimensional survey of our galaxy, allowing them to peer into the inner structure and observe its star-forming processes in unprecedented detail.

The large-scale survey, called SEDIGISM (Structure, Excitation and Dynamics of the Inner Galactic Interstellar Medium), has revealed a wide range of structures within the Milky Way, from individual star-forming clumps to giant molecular clouds and complexes, that will allow astronomers to start pushing the boundaries of what we know about the structure of our galaxy.

SEDIGISM has been unveiled today through the publication of three separate papers in the Monthly Notices of the Royal Astronomical Society, authored by an international team of over 50 astronomers.

“With the publication of this unprecedentedly detailed map of cold clouds in our Milky Way, a huge observational effort comes to fruition,” says Frederic Schuller from the Max Planck Institute for Radio Astronomy (MPIfR),

Jupiter and Saturn to appear closest in night sky in hundreds of years

Keep a close look at the sky in December and you may see a very rare event.

Keep a close look at the night sky in December and you may see a rare occurrence between the two biggest planets in our solar system.

From now until Dec. 21, Jupiter and Saturn will continue to get closer until they are just 0.1 degrees apart and form a “double planet,” according to NASA. And there’s a chance you’ll be able to see it for yourself.

The space agency describes the rarity of the 2020 event in-depth in its December Skywatching page. The rare event is officially called a “great conjunction.”

“These occur every 20 years this century as the orbits of Earth, Jupiter, and Saturn periodically align making these two outer planets appear close together in our nighttime sky,” NASA writes.

One million new galaxies found in fastest radio survey of the sky yet


The most rapid radio survey of the southern sky has been completed by the Australian SKA Pathfinder telescope.


The most detailed and most rapid survey of the southern sky has helped map about a million previously undiscovered galaxies. Using the Australian Square Kilometre Array Pathfinder radio telescope, scientists from the CSIRO, Australia’s national science agency, have cut the time to complete such an intense survey of space from years to less than two weeks.

In a study, published in the journal Publications of the Astronomical Society of Australia on Monday, the first results from the CSIRO’s Rapid ASKAP Continuum Survey are reported. The agency describes the survey as like a “Google Map” of the universe, providing the most detailed atlas of the southern sky yet. 

The key to the new atlas is ASKAP, which

Bright Fireball Lights Up Night Sky In Japan Over The Weekend [VIDEO]


  • A bright fireball was spotted in western Japan, on Sunday
  • Several cameras captured the moment that the bolide illuminated the surroundings
  • The event was reportedly seen in various regions in Western and Central Japan

A fireball event was spotted in Japan over the weekend. The event was so bright that it momentarily lit up the night sky. 

A bright fireball was spotted at about 1:34 a.m. local time, Sunday in western Japan. According to the International Meteor Organization (IMO), witnesses said that there was a “rumbling noise” then the sky went “totally bright.”

In the video shared by Japan Broadcasting Corporation, NHK on Twitter, a bright greenish ball can be seen streaming in the sky at various locations. It can be seen falling for a few seconds before illuminating the night sky for a brief moment then fizzling out in an instant.

December Sky Events To Look Forward To


  • December is packed with exciting sky events
  • The 14th will feature a meteor shower and a total solar eclipse
  • A very special conjunction between Jupiter and Saturn will also happen this month

Skywatchers are in for a treat this December. From a total solar eclipse to the rare conjunction of Jupiter and Saturn, December is sure to give them a reason to look up.

Geminid Meteor Shower

From the evening of Dec. 13 to the morning of Dec. 14, what NASA described as “one of the best meteor showers of the year” will peak. As the agency explained, 2020 is a good year to observe the Geminids, which could showcase 140 to 150 visible meteors per hour.

With clear skies and ideal conditions, skywatchers should be able to observe the Geminids throughout the night since its peak is quite broad, NASA said. What’s more, there will be no

How SpaceX Starlink broadband will envelop Earth and transform the sky

When the call connects and I ask Angel Chavarin if I’m speaking to AWN-hell or AIN-gel, there’s a familiar pause. I can hear the faint echo of my own words finally reach the cellphone’s speaker on the other end of the line a few seconds later, and then a voice responds:

“Yep, it sure is. AIN-gel works. No one around here calls me AWN-hell except my dad.”

It’s a delay I recognize from using satellite phone connections while on assignment on the Alaskan tundra and other remote areas. The signal carrying my words must travel over 22,000 miles (35,000 kilometers) to a satellite in geostationary orbit and then another 22,000 miles back to Earth to reach the person on the other end of the call.

Don’t miss Jupiter, Saturn and the moon forming a triangle in the sky tonight


The moon will put on a show Thursday night with Jupiter and Saturn.

It’s thoughtful of the night sky to offer so many good views with so many people stuck at home. From the Leonid meteor shower to Halloween’s blue moon, skywatchers have been spoiled recently. And here’s another goodie: Head outside Thursday night to see the moon, Saturn and Jupiter form a neat triangle. The crescent moon will be visible in the south-southwest as soon as the sky darkens, but the other two show up a little later. Jupiter should make an appearance after sunset, and Saturn a little later on.

“The best observing time is about 30 minutes after local sunset for about two hours while the moon and planets are high enough in the sky to

Sky Q To Get 40+ HDR Films By Christmas

After a couple of relatively quiet years, British satellite broadcaster Sky is continuing its recent resurgence in 2020 by adding more than 40 films to its burgeoning portfolio of high dynamic range (HDR) titles – all set to arrive in time for Christmas. 

Sky can’t yet reveal the full list of HDR movies it’s going to be making available through its Sky Cinema service, but it is confirmed that the Back To The Future Trilogy, Dolittle, Le Mans 66, and all 8 Harry Potter films will be available in HDR from December 9. New Premieres including Emma, Little Women and Bad Boys For Life will also be landing in HDR when they join Sky Cinema – and Sky Original film The Secret Garden is actually available in HDR now.

It’s nice to see that Sky is prioritising getting HDR movies on Sky Cinema, within a suitable subscription,

Dark sky sets the stage for meteors, planets and constellations

The new moon occurs on Sunday, Nov. 15, at 12:07 a.m. EST (0507 GMT), just two days before the Leonid meteor shower reaches its peak. Without any moonlight to pollute the view, skywatchers may see some meteors in the night sky. Jupiter, Saturn and Mars will reign in the evening sky, while Mercury and Venus will make a special appearance before dawn the next day.

New moons occur when the moon is between the sun and Earth. About every 29.5 days the two bodies are lined up in the sky along the same line of celestial longitude. Celestial longitude is a projection of the Earth’s longitude lines on the celestial sphere; when two bodies share the same longitude that is called a conjunction. If one draws a
