NASA Glenn Looking to Lease Facilities

As NASA advances its aviation and spaceflight missions, its facilities and infrastructure need to evolve along with them. NASA centers, including Glenn Research Center in Cleveland, must find ways to reduce the cost of maintaining assets they aren’t currently using.

Toward this goal, NASA Glenn is offering opportunities to lease assets it no longer uses. These Enhanced Use Lease (EUL) agreements will allow space, aeronautics, and other related industry to use Glenn land and facilities in direct support of NASA’s mission. It’s an arrangement that could bring some of the best minds in aerospace closer together, spurring innovation.

“We want to strategically align Glenn’s unique aircraft and spacecraft testing assets with the aviation industry and emerging commercial market,” said Carlos Flores, NASA Glenn’s Strategic Planning Branch chief. “Our hope is to expand partnerships, accelerate innovation, and create regional economic opportunities.”

Flores said there are many advantages for commercial entities to lease NASA facilities. These partners will have more access to resources—such as other facilities and technical expertise— than those outside the gate.

“Once a company or university gets a foot in the door, it is very possible they will discover other assets and expertise they can leverage,” Flores said.

Glenn identified four facilities in Cleveland and one in Sandusky, Ohio, that will be considered under the EUL authority. They include:

In March, Glenn released an Announcement for Proposal, or AFP, to the public soliciting offers for the use of the Cryogenics Components Laboratory at NASA’s Neil Armstrong Test Facility in Sandusky. An AFP is expected for the Altitude Combustion Stand in Cleveland within a couple of months.

Glenn and other NASA centers continually work to align their facilities and infrastructure with the Agency Master Plan, which serves as a roadmap for future development and redevelopment of agency property.

To align with the Agency Master Plan, Glenn must reduce its “maintenance gap,” which is the amount of property owned versus the amount of property the center can afford to maintain.

“The maintenance gap is one of the realities we face in an environment of current and future budget constraints,” Flores said. 

While demolition is sometimes the easiest way to reduce square footage and maintenance costs, leasing can be a viable option for buildings that do not fit the demolition criteria.

“EULs will not only reduce the maintenance gap and the square footage we are responsible to maintain, but they will also enable us to create strategic partnerships and utilize revenue from the base rent for repairs to infrastructure,” Flores said.

Hubble Glimpses a Star-Forming Factory

NASA - Breaking News - Fri, 05/10/2024 - 7:18am

Hubble Glimpses a Star-Forming Factory This image from the NASA/ESA Hubble Space Telescope highlights the spiral galaxy UGC 9684.

The celestial object showcased in this image from the NASA/ESA Hubble Space Telescope is the spiral galaxy UGC 9684, which lies around 240 million light-years from Earth in the constellation Boötes. This image shows an impressive example of several classic galactic features, including a clear bar in the galaxy’s center, and a halo surrounding its disk.

The data for this Hubble image came from a study of Type-II supernovae host galaxies. These cataclysmic stellar explosions take place throughout the universe, and are of great interest to astronomers, so automated surveys scan the night sky and attempt to catch sight of them. The supernova which brought UGC 9684 to Hubble’s attention occurred in 2020. It has since faded from view and is not visible in this image, which was taken in 2023.

Remarkably, the 2020 supernova isn’t the only one that astronomers have seen in this galaxy – UGC 9684 has hosted four supernova-like events since 2006, putting it up there with the most active supernova-producing galaxies. It turns out that UGC 9684 is a quite active star-forming galaxy, calculated as producing one solar mass worth of stars every few years! The most massive of these stars are short-lived, a few million years, and end their days as supernova explosions. This high level of star formation makes UGC 9684 a veritable supernova factory, and a galaxy to watch for astronomers hoping to examine these exceptional events.

Astronomers are on the Hunt for Dyson Spheres

Universe Today - Thu, 05/09/2024 - 4:57pm

There’s something poetic about humanity’s attempt to detect other civilizations somewhere in the Milky Way’s expanse. There’s also something futile about it. But we’re not going to stop. There’s little doubt about that.

One group of scientists thinks that we may already have detected technosignatures from a technological civilization’s Dyson Spheres, but the detection is hidden in our vast troves of astronomical data.

A Dyson Sphere is a hypothetical engineering project that only highly advanced civilizations could build. In this sense, ‘advance’ means the kind of almost unimaginable technological prowess that would allow a civilization to build a structure around an entire star. These Dyson Spheres would allow a civilization to harness all of a star’s energy.

A Civilization could only build something so massive and complex if they had reached Level II in the Kardashev Scale. Dyson Spheres could be a technosignature, and a team of researchers from Sweden, India, the UK, and the USA developed a way to search for Dyson Sphere technosignatures they’re calling Project Hephaistos. (Hephaistos was the Greek god of fire and metallurgy.)

They’re publishing their results in the Monthly Notices of the Royal Academy of Sciences. The research is titled “Project Hephaistos – II. Dyson sphere candidates from Gaia DR3, 2MASS, and WISE.” The lead author is Matías Suazo, a PhD student in the Department of Physics and Astronomy at Uppsala University in Sweden. This is the second paper presenting Project Hephaistos. The first one is here.

“In this study, we present a comprehensive search for partial Dyson spheres by analyzing optical and
infrared observations from Gaia, 2MASS, and WISE,” the authors write. These are large-scale astronomical surveys designed for different purposes. Each one of them generated an enormous amount of data from individual stars. “This second paper examines the Gaia DR3, 2MASS, and WISE photometry of ~5 million sources to build a catalogue of potential Dyson spheres,” they explain.

Combing through all of that data is an arduous task. In this work, the team of researchers developed a special data pipeline to work its way through the combined data of all three surveys. They point out that they’re searching for partially-completed spheres, which would emit excess infrared radiation. “This structure would emit waste heat in the form of mid-infrared radiation that, in addition to the level of completion of the structure, would depend on its effective temperature,” Suazo and his colleagues write.

The problem is, they’re not the only objects to do so. Many natural objects do, too, like circumstellar dust rings and nebulae. Background galaxies can also emit excess infrared radiation and create false positives. It’s the pipeline’s job to filter them out. “A specialized pipeline has been developed to identify potential Dyson sphere candidates focusing on detecting sources that display anomalous infrared excesses that cannot be attributed to any known natural source of such radiation,” the researchers explain.

This flowchart shows what the pipeline looks like.

This flowchart from the research illustrates the pipeline the team developed to find Dyson Sphere candidates. Each step in the pipeline filters our objects that don’t match the expected emissions from Dyson Spheres. Image Credit: Suazo et al. 2024.

The pipeline is just the first step. The team subjects the list of candidates to further scrutiny based on factors like H-alpha emissions, optical variability, and astrometry.

368 sources survived the last cut. Of those, 328 were rejected as blends, 29 were rejected as irregulars, and 4 were rejected as nebulars. That left only 7 potential Dyson Spheres out of about 5 million initial objects, and the researchers are confident that those 7 are legitimate. “All sources are clear mid-infrared emitters with no clear contaminators or signatures that indicate an obvious mid-infrared origin,” they explain.

This pie chart shows the breakdown of the 368 sources that made it through the filter. Only 7 objects out of millions are labelled Dyson Sphere candidates. Image Credit: Suazo et al. 2024.

These are the seven strongest candidates, but the researchers know they’re still just candidates. There could be other reasons why the seven are emitting excess infrared. “The presence of warm debris disks surrounding our candidates remains a plausible explanation for the infrared excess of our sources,” they explain.

But their candidates seem to be 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. One type of debris disk called Extreme Debris Disks (EDD) can explain some of the luminosity the team sees around their candidates. “But these sources have never been observed in connection with M dwarfs,” Suazo and his co-authors write.

That leaves the team with three questions: “Are our candidates strange young stars whose flux does not vary with time? Are these stars’ M-dwarf debris disks with an extreme fractional luminosity? Or something completely different?”

This figure from the research shows the seven candidates plotted on a colour-magnitude diagram. It indicates that all seven are M-dwarfs. Image Credit: Suazo et al. 2024.

“After analyzing the optical/NIR/MIR photometry of ~5 x 106 sources, we found 7 apparent M dwarfs exhibiting an infrared excess of unclear nature that is compatible with our Dyson sphere models,” the researchers write in their conclusion. There are natural explanations for the excess infrared coming from these 7, “But none of them clearly explains such a phenomenon in the candidates, especially given that all are M dwarfs.”

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. “In particular, analyzing the spectral region around H-alpha can help us ultimately discard or verify the presence of young disks,” the researchers write.

“Additional analyses are definitely necessary to unveil the true nature of these sources,” they conclude.
