‘Oumuamua: Alleged Alien Craft Images (Telescoped+Hubble)

‘Oumuamua remains the first and (thus far) only interstellar visitor we’ve caught skipping through our solar system. The data available on it are limited, but that doesn’t stop researchers around the world from wondering what they can find within its depths. “What’s especially fascinating is that people are still writing papers on it,” says Meech, “even though we effectively got a couple weeks of data with everyone trying, and then the HST and the Spitzer data went a little longer, but that’s it. And people are still writing papers."

What’s more, A recent TED talk Meech gave on ‘Oumuamua currently has more than 2 million views and is continuing to gain more, she says. “Clearly people are interested.”

It’s certainly an interesting object. Its strange properties have even prompted some to suggest it’s of truly alien — as in, alien-built — origin. But those arguments don’t really hold up against the data we do have, Meech says, limited though it may be.

So while it’s not an alien spaceship or an artificial light sail, ‘Oumuamua is still a mysterious, transient visitor that has captured the attention of researchers and the public alike.

Below are some interesting images of ‘Oumuamua

This very deep combined image shows the interstellar object ‘Oumuamua at the center of the image. It is surrounded by the trails of faint stars that are smeared as the telescopes tracked the moving comet. The image was created by combining multiple images from the European Southern Observatory’s Very Large Telescope as well as the Gemini South Telescope. The object is marked with a blue circle and appears to be a point source, with no surrounding dust.

On January 2nd 2018, the Hubble Space Telescope has again imaged the interstellar asteroid 1I/'Oumuamua. At magnitude +27.5, it is now at the limit of what Hubble can reliably detect in a single orbit, so this will be the last image of the remarkable object 1I/'Oumuamua.

It’s so cold, Canada is colder than Mars

On Dec. 27, the temperature on Mars reached about -20°F. In Saskatoon, Canada the temperature was -45°F. Ottawa, Montreal, Toronto, and Calgary are experiencing colder temperatures (with wind chill) than daytime Mars, though at night, the temperature on the red planet plunges to below -100°F. It’s so cold in Canada that electric poles are snapping in Nova Scotia, windows are breaking spontaneously, most ice skating has been canceled, and even Toronto’s famous polar bear plunge was postponed for the first time in 13 years.

V-2 Rockets In Australia? It Happened

The story of V-2 ended up Down Under is an intriguing one that involves science, politics and Cold War anxieties.

Australia's two V-2s are currently in storage at an Australian War Memorial (AWM) facility in suburban Canberra.

"When they came out [to Australia] flocks of people crowded to view them and see these Nazi terror weapons," said Shane Casey, senior curator of military heraldry and technology at the AWM.

One is mostly complete. Its components were seized after the war and put together as part of Operation Backfire, a mission by the Allies to capture and test German military technology.

"When the Allies conquered Germany, they found largely disassembled rockets or rockets ready to be assembled," Mr Casey said.

The Meillerwagen trailer accompanying the V-2, which was used to raise the rockets onto launch pads, is one of the few surviving examples of the technology.

The other V-2, which left London's docks aboard the vessel Karamea in February 1947, is today in bits, which are themselves in disrepair. It was shipped to Australia primarily as a museum piece, and little is known about its origins.

"There was some confusion as to whether it was destined for the Australian War Memorial or whether it was destined for the RAAF at Woomera. There seems to have been some dissension in official channels about that."

The missile was trucked around the country as part of a fundraising mission, and video shows it outside Old Parliament House. One of the purposes of having the rockets in Australia was to boost public interest in science, especially the emerging field of space research.

In 1948, the media was invited to view the more complete V-2 at Salisbury, where scientists had been inspecting it for design clues. That work was part of efforts to develop a local rocket program for defence - a project that also included the Woomera range. At some point over the next few years, it was painted with a different colour scheme. The trail goes cold until 1954, when the rocket was put on display at a Salisbury school and at the Mallala air show.

By the late 60s, Australia became the third nation to design and launch a satellite to orbit the earth. Design work on Australia’s first satellite began in early 1967 as a joint venture between the Weapons Research Establishment (WRE) and the University of Adelaide. With, The US and the UK providing assistance on the project, including the US Department of Defense, NASA, and the UK’s Ministry of Technology.
