Massive telescope collapse caught on remote camera and drone in Puerto Rico – CBC.ca

The National Science Foundation (NSF) has released new footage of the collapse of the Arecibo telescope platform in Puerto Rico.

The 57-year-old radio telescope suffered major damage in August when one of the cables supporting the platform snapped. Another cable snapped in early November.

Then, on Tuesday, the entire platform came crashing 122 metres onto the dish below.

The telescope at Arecibo, Puerto Rico, was once the world’s largest single-dish radio telescope. Seen here in better days, it was already set to be decommissioned following irreparable damage earlier in 2020. (Arecibo Observatory)

“We are saddened by this situation but thankful that no one was hurt,” NSF Director Sethuraman Panchanathan said in a statement. “When engineers advised NSF that the structure was unstable and presented a danger to work teams and Arecibo staff, we took their warnings seriously.”

The telescope has been used to track asteroids on a path to Earth, conduct research that led to a Nobel Prize and determine if a planet is potentially habitable. It also served as a training ground for graduate students and drew about 90,000 visitors a year.

“I am one of those students who visited it when young and got inspired,” said Abel Mendez, a physics and astrobiology professor at the University of Puerto Rico at Arecibo who has used the telescope for research. “The world without the observatory loses, but Puerto Rico loses even more.”

Arecibo has also been featured in movies such as Contact and the James Bond film GoldenEye.

How a Vancouver photographer captured this epic night shot of The Lions | News – Daily Hive

Published

 on


At only 20 years old, Vancouver photographer Liron Gertsman already has an impressive resume.

His work has been featured in some of the largest museums across the world, including the Natural History Museum in London and the Smithsonian in Washington, DC.

And while his latest work may be closer to home, it features worlds far beyond our own.

“There is so much to see if you can get outside on a clear night and look up at the sky,” he told Daily Hive. “Stargazing is a fantastic pandemic activity.”

But beyond just simply “gazing” at the stars, Gertsman recently captured this stunning photo of the North America and Pelican Nebulae in what’s known as the Cygnus region of the night sky, above The Lions on the North Shore.

Describing it as “one of the most ambitious” photos he’s ever attempted, Gertsman shared how it all came, from planning and execution to the final product.

“I first imagined this photo a few months ago,” he said. “While running virtual simulations on my computer, I was astonished to see that the North America Nebula, a huge cloud of gas over 2200 light years from Earth, would align perfectly with The Lions, if I was in the right place at the right time.”

However, he also realized that capturing the photo would require that he take the picture from a “heavily light-polluted” area.

As such, Gertsman said he “wasn’t convinced” that the image he was trying to capture was even possible.

The other factor putting doubt in his mind was the typical wet weather Vancouver receives during the winter months.

“This is a rainforest, and clear skies can be very rare in winter,” he said.

After waiting for a few months, Gertsman was rewarded for patiently biding his time, as the opportunity presented itself on the night of January 21.

“I would be battling a 62% illuminated moon, but given the rarity of the clear night, I decided to attempt the image,” he said.

The attempt included waiting in the cold for three-and-a-half hours, and gathering long exposure data on the nebulae as it moved across the sky, until it was directly above The Lions.

The final image includes two hours of exposure time, taken without movement of his tripod.

As for his setup, Gertsman said he used a full-spectrum modified Canon 6D and a Canon 100-400mm lens at 200mm, mounted on a SkyWatcher star tracker. He also used three filters:

First, one that allows visible light to pass through but extends further than normal to the 656nm H-alpha wavelength emitted by nebulae. This data, he explained, was important for “gathering accurate colour.”

Second, an H-alpha filter, which selectively allows the 656nm wavelength of the nebula through while blocking out most moonlight and light pollution.

Third, a normal visible light filter, to gather natural colours for the foreground.

These images were combined, stacked, and stretched in post-processing to create this final image.

How to watch NASA preview its Perseverance Mars rover landing – CNET

NASA is just weeks away from landing a shiny new robot on the surface of Mars. This Wednesday it’ll break down for us the process of setting the Mars 2020 Perseverance rover on the surface of the red planet.

Perseverance is due to land in Jezero Crater on Feb. 18, the first artificial object to land on the surface since the Mars Insight lander in 2018 and the first rover since Curiosity touched down in 2012.

Perseverance carries a number of science instruments to help look for signs of ancient life on our neighboring world, to collect samples that will be returned to Earth and to test some technologies for future Mars missions.

Also, it has a tiny helicopter.

Robots have spent years rolling around Mars, which is pretty cool, but for the first time NASA will use a small helicopter, dubbed Ingenuity, to try flying around the planet.

Several leaders from the Mars 2020 Perseverance team will be on hand Wednesday to discuss the mission and run through what landing day will look like.

The briefing is scheduled for 1:30 p.m. ET, and you can watch it all live right here.

First full moon of 2021 might be tough to see this week | iNFOnews | Thompson-Okanagan's News Source – iNFOnews

January 26, 2021 – 6:30 AM

The first full moon of 2021 and the second one of the winter season will be viewable over Kamloops and the Okanagan later this week.

The second full moon of the season, known variously as the Wolf, Snow or Hunger Moon, will look visibly full on Jan. 27 and 28, but in astronomical terms it is at its fullest on Jan. 28 at 11:16 a.m., Pacific time, when daytime might make it a bit difficult to see.

Earthsky.org says to expect to see a full-looking moon in the east at dusk or early evening. The moon should appear full to the average viewer the night before and the night after its Jan. 28 peak.

Unfortunately for us in Kamloops, Vernon, Kelowna and Penticton, this month’s Wolf Moon might prove difficult to view at any time during the next few days.

Environment Canada is calling for mainly cloudy skies with periods of snow or flurries from Tuesday night, Jan. 26 through Friday, Jan. 29, with a hint of sun forecast for Friday, so keep an eye out for a break in the clouds.

The next full moon is the Snow Moon, expected on Feb. 27.
