NASA, ESA, CSA, STScI Two actively forming stars are responsible for the shimmering hourglass-shaped ejections of gas and dust that gleam in orange, blue, and purple in this representative color image captured by NASA’s James Webb Space Telescope. This star system, called Lynds 483, is named for American astronomer Beverly T. Lynds, who published extensive catalogs of “dark” and “bright” nebulae in the early 1960s.
The two protostars are at the center of the hourglass shape, in an opaque horizontal disk of cold gas and dust that fits within a single pixel. Much farther out, above and below the flattened disk where dust is thinner, the bright light from the stars shines through the gas and dust, forming large semi-transparent orange cones.

Additive manufacturing, also known as 3D printing, is regularly used on the ground to quickly produce a variety of devices. Adapting this process for space could let crew members create tools and parts for maintenance and repair of equipment on the spot, rather than trying to bring along every item that might be needed.
The ability to manufacture things in space is especially important in planning for missions to the Moon and Mars because additional supplies cannot quickly be sent from Earth and cargo capacity is limited.
Research on the International Space Station is helping to develop the capability to address multiple needs using 3D printing.
NASA astronaut Jeanette Epps configures the Metal 3D Printer to produce experimental samples from stainless steel.NASA Metal 3D Printer, a current investigation from ESA (European Space Agency), tests 3D printing of small metal parts in microgravity. Results could improve understanding of the function, performance, and operations of 3D printing in space with metal, as well as the quality, strength, and characteristics of printed parts. This work also could benefit applications on Earth that use metal, such as the automotive, aeronautical, and maritime industries.
Printing with plastic
NASA Astronaut Butch Wilmore holds a ratchet wrench created with the 3D Printing in Zero-G printer.NASA 3D Printing in Zero-G sent the first 3D printer, developed by NASA’s Marshall Space Flight Center and Redwire (formerly Made in Space), to the space station in 2014. The printer used a process that feeds a continuous thread of plastic through a heated extruder and onto a tray layer by layer to create an object. The investigation produced more than a dozen parts, including a ratchet wrench, showing that researchers could send a design from the ground to the system on the station more than 200 miles above.
Comparing the parts made in space with those made on the ground showed that microgravity had no significant effect on the process.
Redwire then developed the Additive Manufacturing Facility (AMF), sent to the station in 2015. Researchers evaluated its mechanical performance and found improvements in tension strength and flexibility compared to the earlier demonstration, helping to further the technology for this type of manufacturing on Earth and in space.
In 2015 and 2016, Portable On Board 3D Printer tested an automated printer developed by the Italian Space Agency to produce plastic objects in space. The investigation provided insight into how the material behaves in microgravity, which could support development of European additive manufacturing technology for use in space.
Printing with other materials
NASA astronaut Anne McClain installs the Refabricator in Feb. 2019.NASA Another approach is recycling plastic – for example, turning a used 3D-printed wrench into a spoon and creating items from the plastic bags and packing foam needed to send supplies to space. This technology could help reduce the amount of raw material at launch and cut down on the volume of waste that must be disposed of on long journeys. The Refabricator, a machine created by Tethers Unlimited Inc, tested this approach and successfully manufactured its first object. Some issues occurred in the bonding process, likely caused by microgravity, but assessment of the material could help determine whether there are limits to how many times plastic can be re-used. Ultimately, researchers plan to create a database of parts that can be manufactured using the space station’s capabilities.
The Redwire Regolith Print facility before launch to the space station.Redwire Space Redwire Regolith Print (RRP) tested another kind of feedstock for 3D manufacturing in orbit, a simulated version of regolith, the dust present on the surface of the Moon and other planetary bodies. Results could lead to development of technology for using regolith to construct habitats and other structures rather than bringing raw materials from Earth.
The space station also has hosted studies of a form of 3D printing called biological printing or bioprinting. This process uses living cells, proteins, and nutrients as raw materials to potentially produce human tissues for treating injury and disease, which could benefit future crews and patients on Earth.
Other manufacturing techniques tested on the orbiting lab include producing optical fibers and growing crystals for synthesizing pharmaceuticals and fabricating semiconductors.

On March 26, 2020, a French astronomer Mark Carlotto used a telescope to capture a video showing the moon at night. Dr. M. Carlotto is a specialist in digital video analysis of space objects. The video shows three objects rising above the Moon’s limb, flying across the lunar surface and disappearing in the Moon’s shadow.
The fact that some of these objects are so clearly visible and close enough to the moon to be able to cast noticeable shadows immediately suggests that they are quite large. Using the large Endymion crater as a benchmark, the sizes of the objects were determined.
The size of the object flying over Endymion is about 5 miles long and about 1 to 3 miles wide. The other two objects appear to be comparable in size.
By measuring the displacement of the object it appears that the object is traveling at about 31 mps. It is traveling more than 30 times faster than if it were in lunar orbit.
A paper was recently published that attempts to prove that the original video is a fake. Arxiv.org analyzed the video (not included in the analysis) but extracted and provided three images of the recorded objects for examination, as seen above, and they then conducted calculations to verify its authenticity.
Despite government and space agency denials of UFO existence, photographic evidence and subsequent analysis suggest the presence of large extraterrestrial craft near the Moon and elsewhere in space.View the full article

In the depths of the ocean, where countless strange fish and creatures dwell in perpetual darkness, they remain unseen, unless unexpectedly caught. This was the case during an expedition by a Russian deep-sea fisherman, who was stunned when he reeled in a bizarre creature that strikingly resembled an alien’s head.
The eerie catch was made by Roman Fedortsov during an expedition in the northern Pacific Ocean.
The fisherman shared the video of the strange creature with his followers, with viewers comparing the bulbous fish to an extraterrestrial or even Krang, the villain from Teenage Mutant Ninja Turtles.
Fisherman Fedortsov has previously made headlines thanks to other weird and wonderful catches which you can view at Dailymail.
Despite its eerie appearance, the fish was not an alien or a mutant but rather a species known as the smooth lumpsucker, a deep-sea fish recognized for its distinctive, gelatinous look.

CCOR-1, a newly activated coronagraph onboard NOAA’s GOES-19 weather satellite, is the first of its kind in geostationary orbit. Positioned deep inside the Moon’s orbit, it offers a perspective unavailable to previous coronagraphs like those on SOHO.
New Moons are typically dark and invisible, but NOAA's CCOR-1 coronagraph just captured one in stunning detail.
In the footage, the Moon appears full, an illusion caused entirely by sunlight reflecting off Earth. The brightness isn’t constant, though. As sunrise progresses over the Western Hemisphere, the increasing Earthshine becomes so intense that some frames are saturated with light.
