First Colored Image of Interstellar Comet Captured by Gemini Observatory – Interesting Engineering

Published

on


The multi-colored image of a comet from beyond our Solar System has been captured for the very first time by the Gemini Observatory.

The Gemini North Observatory, based on the top of Mauna Kea in Hawai’i, caught the moment on the night of September 9th and 10th. 

The comet is named C/2019 Q4, or Borisov Comet, and is a newly discovered interstellar comet. 

What’s also interesting for astronomers is that this interstellar comet may share more similarities with comets in our Solar System than was previously known.

What exactly did the Gemini North Observatory capture?

Gennady Borisov, a Ukrainian amateur astronomer, first saw the comet on 30 August, giving the comet its more colloquial name: the Borisov comet. 

Following Borisov’s discovery, the Germini North Observatory also captured an image of the comet with four 60-second exposures. The astronomers in Hawai’i were able to capture the comet in multi-color. 

Displaying a pronounced tail, demonstrating outgassing — meaning the release of gas from within a solid — is what made it clear that this is a comet.

What’s exciting is that this is the first time an interstellar comet from beyond our Solar System has shown a tail due to outgassing. Previously, the only other ‘visitor’ from outside our Solar System was ‘Oumuamua in 2017.

‘Oumuamua was an elongated asteroid-looking object that did not display any outgassing. As it was traveling quickly away from our Solar System, astronomers did not have the chance to find out what it was made of, but they figured it out that it was not a comet.

The image of the comet had to be quickly snapped, as Andrew Stephens of the Gemini Observatory who coordinated the observations said: “This image was possible because of Gemini’s ability to rapidly adjust observations and observe objects like this, which have very short windows of visibility.” 

Stephens continued, “However, we really had to scramble for this one since we got the final details at 3:00 am and were observing it by 4:45!”

The team in Hawai’i hopes to capture more images of the comet over the next few months, as it travels nearer and nearer to us. 

Currently, the Borisov comet is hard to observe closely as it is near the position of our Sun. The comet’s hyperbolic path — which is what determined that it originated outside our Solar System — will be moving it to more favorable viewing points, hopefully allowing astronomers to capture more images.

A giant full beaver moon set to dazzle Metro Vancouver skies – Vancouver Courier

Published

By


While it is getting darker earlier in Metro Vancouver, this month’s full beaver moon promises to illuminate the night sky.

The November full moon is thought to have derived its funny name because it occurred during the optimal time to trap the furry creatures. In fact, both colonial Americans as well as the Algonquin tribes referred to it as such.

article continues below

“Why this name? Back then, this was the month to set beaver traps before the swamps froze, to ensure a supply of warm winter furs,” reports Farmer’s Almanac.

While it is commonly known as the beaver moon, it was also called the Full Frost Moon by other North American Tribes.

According to the Old Farmer’s Almanac, the moon will be fullest during the day on Tuesday, Nov. 12. However, Vancouver stargazers will still be able to see the nearly-full moon in all her celestial glory the night before (Nov. 11) as well as later that night (Nov. 12).

What’s more, this full moon casts long, hauntingly beautiful shadows in the Northern Hemisphere. They are similar to those cast by the midday summer sun, as the moon is extremely high in the sky during this time.

Stargazers should opt to travel as far away from city lights as possible in order to avoid light pollution that will obscure the clarity of heavenly bodies. While this works best the in more remote places, anywhere that has a higher elevation will also provide more ideal viewing conditions.

All-female space walk a starry-eyed achievement: The Statesman – The Straits Times

Published

By


NEW DELHI (THE STATESMAN/ASIA NEWS NETWORK) – It is a starry-eyed achievement almost literally.

Christina Koch and Jessica Meir, two NASA astronauts, have crafted space history by embarking on what they call the first all-female space walk.

Tasked with replacing a failed power control unit, their performance has been decidedly spectacular as they floated feet-first out of the International Space Station’s (ISS) Quest airlock on Friday (Oct 18).

The spacewalk, known as an extra-vehicular activity (EVA) in the jargon of astronauts, took place seven months after the originally scheduled date for an “all-female outing”, which had to be dropped because the ISS had only one medium-sized spacesuit on board.

The agency sent up a second medium spacesuit in October.

From space to ground zero, the happiest thought at the moment must be that both the achievement and empowerment of women are now manifest in the rarified atmosphere of space.

Very appropriately has the significance of the spacewalk been summed up by Christina: “I think it’s important because of the historical nature of what we’re doing,” she said ahead of the spacewalk.

“In the past, women haven’t always been at the table. It’s wonderful to be contributing to the space programme at a time when all contributions are being accepted, when everyone has a role. That can lead in turn to increased chance for success.”

On closer reflection, more than the space-walk, it is the assignment that is historic to fix a failed power control unit.

Previously, 14 women and 213 men had carried out spacewalks. The first woman was the Russian cosmonaut Svetlana Savitskaya, who went outside the USSR’s Salyut 7 space station in 1984.

Video footage from the astronauts’ helmet cameras, as they dangled 260 miles above Earth, provided a live stream of the painstaking operation to carry the new hardware, install it and then return the faulty battery to the airlock for a postmortem back on Earth into why it failed.

Their work in space will, therefore, be followed up by the labs on Earth.

Exceptional must be the projected coordination between space science and pure science as the world knows it.

At 40, Christina is due to remain on the ISS until February, bringing her total time in space to 328 days, the longest single spaceflight by a woman and just short of Scott Kelly’s 340-day record.

Researchers are collecting extensive biomedical data on the impact of spaceflight on her system.

The majority of data available is on male astronauts, but there is some evidence that there are sex differences in response to a space environment.

One study found that women are more likely than men to suffer faintness as a result of “orthostatic hypotension”, a cardiovascular issue.

Men appear more prone to vision changes caused by spaceflight associated neuroocular syndrome (Sans).

A flight to space has a lot to bear on human health. The contretemps notwithstanding, NASA has reached a milestone.

NASA Invites Media to Next SpaceX Space Station Cargo Launch – PRNewswire

Published

on

By



WASHINGTON, Oct. 22, 2019 /PRNewswire/ — Media accreditation is open for the launch of the next SpaceX delivery of science investigations, supplies, and equipment to the International Space Station.

A SpaceX Dragon cargo spacecraft is scheduled to launch on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station (CCAFS) in Florida no earlier than Wednesday, Dec. 4 at 12:48 p.m. EST.

Media prelaunch and launch activities will take place at NASA’s Kennedy Space Center and neighboring CCAFS. Credentialing deadlines are as follows:

  • International media without U.S. citizenship must apply by 4:30 p.m. EDT Sunday, Oct. 27.
  • U.S. media must apply by 4:30 p.m. EST Friday, Nov. 15.

All media accreditation requests should be submitted online at:

https://media.ksc.nasa.gov

For questions about accreditation, please email ksc-media-accreditat@mail.nasa.gov. For other questions, contact Kennedy’s newsroom at 321-867-2468.

Each resupply mission to the station delivers scientific investigations in the areas of biology and biotechnology, physical sciences, Earth and space science. Advances in these areas will help to keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars. Space station research through the ISS National Lab also provides opportunities for other U.S. government agencies, private industry, and academic and research institutions, to conduct microgravity research that leads to new technologies, medical treatments, and products that improve life on Earth.

Highlights of space station research that will be facilitated by research aboard this SpaceX Dragon mission include testing the effectiveness of a device to separate and capture water droplets suspended in an air stream, delivering a next-generation spaceborne system to image Earth in higher spectral resolution than currently possible onboard the TERRA satellite, and testing conditions to develop an inexpensive and scalable process to manufacture optical materials in space.

Cargo resupply from U.S. companies ensures a national capability to deliver critical science research to the space station, significantly increasing NASA’s ability to conduct new investigations at the only laboratory in space. This is the 19th SpaceX mission under NASA’s Commercial Resupply Services contract.

The International Space Station is a convergence of science, technology and human innovation that demonstrates new technologies and enables research not possible on Earth. The space station has been occupied continuously since November 2000. In that time, 239 people and a variety of international and commercial spacecraft have visited the orbiting laboratory. The space station remains the springboard to NASA’s next great leap in exploration, including future missions to the Moon and eventually to Mars.
