Gargantuan sunspot 15-Earths wide shoots powerful X-class flare toward Earth, triggering radio blackouts

One of the largest and most active sunspots seen this solar cycle, called AR3664, has expanded over the past few days.
The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center warned of increased solar flare risk from the solar giant on May 7.
AR3664 has become much more magnetically complex, leading to increased solar flare probabilities over the next several days.
Firing out countless powerful solar flares, including a colossal X-class solar flare this morning — peaking at 5:13 a.m. EDT (0913 GMT), this sunspot can cause shortwave radio blackouts on the sunlit side of Earth at the time of the eruption.
This morning, the X-flare caused shortwave radio blackouts across Europe and Africa as seen in provided image.
Sprawling out at almost 124,000 (200,000 kilometers) from end to end, the sunspot is currently 15 times wider than our home planet.
It can be seen from Earth without the need for magnification, however one must avoid direct gaze at the Sun because of the radiations emitted by the Sun.
The vast size of Sunspot AR3664 rivals Carrington's sunspot of 1859 which fired off a series of powerful solar flares and coronal mass ejections resulting in major geomagnetic storms, igniting telegraph offices and triggering auroras as close to the equator as Cuba and Hawaii.
Scientists are keeping a close eye on this ever-growing sunspot while it continues to face Earth.
Though studies suggest Carrington-class solar storms occur every 40 to 60 years or so and we are long overdue, there is no evidence that any CMEs currently en route from previous solar eruptions this week could cause a new Carrington Event, according to Spaceweather.com.

We’re printing organs… in space. Here’s how.

Organ transplant needs the donor & the patient to have exact matching DNA which never happens.
Existing process requires a life-long transplant diet embodying heavy medication to suppress the immunity.
3D Bioprinting identifies a game-changing solution to print identical biological components to receiver's DNA parameters through a 3D modelled digital blueprint.
To create a digital model, the patient's needed organ requires an MRI or CT scan for the virtual replication of the physical organ.
The bioprinting process happens at 3 phases - pre-bioink preparation, bioink usage, and post-bioink preparation.
3D bioengineering of organs directly impacts organ transplant costs, 3D printers costing up to $100K, compared to a $1M-$1.8M transplant surgical expenditure for transplant of organs like hearts.
Reusable rockets by Space X's Falcon XI and Apex Space’s satellites are used for manufacturing facilities in low earth orbit to print organs in zero gravity environments.
Zero-gravity enables zero sedimentation which reduces the need for scaffolding and aids cells to multiply faster than gravitational forces pulling them away from each other.
Post-print can take 20 days to strengthen the printed organ, and a reentry capsule is used to send the printed organs back to Earth for surgical usage.
The aim is to reduce the cost of organs significantly and make organs available to those in need, considering that as of now, 17 people die every day waiting for an organ in the US.

Astronomers are on the Hunt for Dyson Spheres

A group of scientists from Sweden, India, the UK, and the USA developed a way to search for Dyson Sphere technosignatures they’re calling Project Hephaistos, to search for partial Dyson spheres by analyzing optical andinfrared observations from Gaia, 2MASS, and WISE to discover the technosignatures of advanced civilizations called Dyson Spheres.
A Dyson Sphere is a hypothetical engineering project that only highly advanced civilizations could build around a star, enabling them to harness all of its energy, which could be a technosignature recognized by the Project Hephaistos team.
The team developed a special data pipeline to work its way through the combined data of all three of the largest-scale astronomical surveys: Gaia, 2MASS, and WISE to detect sources that display anomalous infrared excesses that cannot be attributed to any known natural source of such radiation.
Combing through all of that data is an arduous task. The pipeline filters out natural objects that emit similar levels of infrared radiation, like circumstellar dust rings, and background galaxies.
They found seven potential Dyson Spheres out of about 5 million initial objects, which are likely M-type (red dwarf) stars, and debris disks around M-dwarfs are very rare. However, it gets complicated because some research suggests that debris disks around M-dwarfs form differently and present differently.
The researchers say that follow-up optical spectroscopy would help understand these 7 sources better. A better understanding of the H-alpha emissions is especially valuable since they can also come from young disks.
Advanced civilizations could build a structure like a Dyson Sphere, which is a hypothetical engineering project that harnesses energy from an entire star. However, only highly advanced civilizations could build something so massive and complex.
The next stage is analyzing the sources around the H-alpha region which can help the team to verify or discard the evaluation of young disks.
The researchers concluded by saying that they would require further analysis to unveil the true nature of these sources.
The Project Hephaistos team is confident that the detection is hidden within our vast troves of astronomical data and that we may already have detected technosignatures from a technological civilization’s Dyson Spheres.

NASA Field Geology Training Prepares Artemis Mission Support Teams

NASA engineers, managers, and flight directors recently traded their cubicles and conference rooms for an ancient volcanic field in the northern Arizona desert to participate in a field geology course aimed at arming them with first-hand experience in what Artemis astronauts will do when they explore the Moon.
The two-and-a-half-day exercise for Artemis mission support teams was a condensed version of the rigorous training astronauts receive to prepare for Artemis missions to the lunar South Pole region, but shares an important purpose.
Small teams led by geology experts from NASA, the USGS (U.S. Geological Survey), and academia studied maps, built hypotheses about the geologic history of the area, and trekked for miles to test whether those hypotheses match reality.
Geology studies help uncover the rich physical history of an area.
Artemis will send astronauts – including the first woman, first person of color, and its first international partner astronaut – to explore more of the lunar surface than ever before prepare for human missions to Mars for the benefit of all.
“The Moon doesn’t have an atmosphere or flowing water like we have here on Earth, and doesn’t have plate tectonics, which are processes that erase a lot of the evidence from the early Earth,” said Jacob Bleacher, chief exploration scientist in the Exploration Systems Development Mission directorate at NASA Headquarters in Washington.
The planned walking paths, known as traverses, frequently changed based on what they were finding.
Teams embraced the principle of 'flexecution' – or flexible execution – a practice that could come into play as astronauts explore the lunar surface and report findings to a backroom of scientists supporting the mission in the Mission Control Center.
Through Artemis, NASA will send astronauts to explore more of the lunar surface than ever before prepare for human missions to Mars for the benefit of all.
In addition to this geology training to build a foundation for mission support teams, another team will conduct simulated moonwalks in the Arizona desert this spring with mockup spacesuits to test hardware and new capabilities, like a heads-up display using augmented reality, for future Artemis missions.

We Need to Consider Conservation Efforts on Mars

Astrobiology is the field of science that studies the origins, evolution, distribution, and future of life in the Universe.
All of our astrobiology missions are focused on Mars because it is considered the most Earth-like environment beyond our planet.
Legal or normative frameworks be adopted to ensure that future Mars missions do not threaten sites where evidence of past or present life might be found.
The search for life on Mars can be traced to the late 19th and early 20th centuries when Percival Lowell made extensive observations.
Ironically, the Viking 1 and 2 missions that discredited the notion of there being life on Mars revealed evidence that water once flowed on its surface.
NASA and China plan to send crewed missions to Mars by 2040 and 2033, respectively, including astrobiology studies, which could threaten the very abodes where evidence of past life could be found.
Conservation measures must be developed and implemented before additional missions are sent to Mars.
Multiple astrobiology missions will travel to the outer Solar System this decade to search for evidence of life on icy moons like Europa, Ganymede, Titan, and Enceladus.
The ability to search for extant or past life without damaging its natural environment is an ethical and scientific necessity.
Exogeoconservation of Mars is an important issue that needs more attention from researchers and practitioners.
