How Can Galaxies Travel Faster Than Light?

Get Astronomy tweets here http://twitter.com/DeepAstronomy

Probably my biggest regret when I made the Hubble Deep Field in 3D video is saying the phrase “these galaxies are racing away from us, in some cases faster than light”.

I had originally thought I was being clever and the comment would spur discussion. instead there was no discussion, only name calling and I mightily regretted putting it in there.

Anyway, this video was a long time coming, I had been meaning to make this for some time to illustrate what I was talking about.

“Farout!” Newfound Object Is the Farthest Solar System Body Ever Spotted

A newly discovered pink-colored object is the most-distant body ever observed in the solar system—and the first object ever found orbiting at more than 100 times the distance from Earth to the sun.

The pink-colored object is nearly four times more distant from the sun than Pluto, and hints at the possibility of an as-yet-undiscovered giant planet farther out.


Donald Trump has ordered the Pentagon to create the US Space Force

The Space Force would constitute the sixth branch of the US armed forces.

The news: During a meeting with the National Space Council today, President Donald Trump directed the Department of Defense and the Pentagon to begin work on the creation of the Space Force. He stated, “‘We are going to have the Air Force and we’re going to have the Space Force, separate but equal.”

Some background: This isn’t the first time Trump has brought up this idea. He has continued to express interest in the idea during visits to West Point and in speeches to military members.


Astronomers have begun mapping the structure of the far side of the Milky Way

This particular region is located over 66,000 light years from Earth and at on opposite side of the Milky Way, relative to our Solar System. The previous record for a parallax measurement was about 36,000 light-years, roughly 11,000 light years farther than the distance between our Solar System and the center of our galaxy. As Sanna explained, this accomplishment in radio astronomy will enable surveys that reach much farther than previous ones:

“Most of the stars and gas in our Galaxy are within this newly-measured distance from the Sun. With the VLBA, we now have the capability to measure enough distances to accurately trace the Galaxy’s spiral arms and learn their true shapes.”

Hundreds of star-forming regions exist within the Milky Way. But as Karl Menten – a member of the MPIfR and a co-author on the study – explained, this study was significant because of where this one is located. “So we have plenty of ‘mileposts’ to use for our mapping project,” he said. “But this one is special: Looking all the way through the Milky Way, past its center, way out into the other side.”

A ‘super blood wolf moon’ and five eclipses are among 2019’s major astronomy events

2019 is featuring five eclipses, a rare planet transit, one of the best meteor showers and a super blood wolf moon, but the fun doesn’t stop there.

The new year will also bring three supermoons, a blue moon, multiple meteor showers, close approach by the moon and Jupiter and several rocket launches.

Although we would love to talk about all of the extraordinary occurrences, these are our top events to watch for in the sky in 2019:


NASA wants you to celebrate New Years with its New Horizons space probe

NASA’s New Horizons spacecraft has been speeding through space since early 2006 and it’s about to make what might be its most interesting flyby to date. After speeding past Jupiter and Pluto in the 12 years since its launch, the probe is about to have a very close encounter with a mysterious object in the outer Solar System called Ultima Thule. As luck would have it, it’s going to meet its target on New Year’s Day, and it’s a pretty big deal for NASA.

As we approach the probe’s arrival at Ultima Thule, NASA is announcing its schedule of events related to the probe’s flyby. The big show will begin on the afternoon of Monday, December 31st, and it’ll kick off three days of news and briefings that will give us our best look yet at an extremely distant Solar System object.

Named ISDApp, from the Tagalog word “isda” meaning fish, the app sends useful information to fishermen such as real-time weather, sunrise and sunset, wind speed, and cloud coverage to plan their fishing activities using the NASA GLOBE Observer app, a data collection from citizen scientists around the world used in concert with NASA satellite data to identify or communicate information, and educate the public about planet Earth
