Sky & TelescopeIndustrial Project Threatens Dark Chilean Skies

When a study in 2023 crowned Cerro Paranal the darkest observatory site in the world, astronomers must have felt reassured to have chosen the right spot. The 2,635-meter (8,645-foot) mountain in Chile’s Atacama Desert is home to the European Southern Observatory’s (ESO) Very Large Telescope, one of the most advanced and prolific astronomical facilities. But now, if a company named AES Andes (a subsidiary of the U.S. power company AES Corporation) gets its way, Paranal’s observational prowess might soon be history: Light pollution emitted by a proposed industrial “megaproject” could do away with the dark skies over this observatory.

National Astronomical Observatory of JapanPrime Focus Spectrograph on the Subaru Telescope to Begin Science Operations in February

Researchers have finished equipping the Subaru Telescope with a new special “compound eye,” culminating several years of effort. This new eye is an instrument featuring approximately 2,400 prisms scattered across the extremely wide field of view available at the Subaru Telescope’s primary focus, allowing for simultaneous spectroscopic observation of thousands of celestial objects. This unrivaled capability will help researchers precisely understand the formation and evolution of galaxies and the Universe. Among 8-meter-class telescopes, the Subaru Telescope is the most competitive with the largest survey capability in the world. This instrument, the Prime Focus Spectrograph (PFS), will be ready to begin scientific operations in February 2025.

NASASimulated Universe Previews Panoramas from NASA’s Roman Telescope

Astronomers have released a set of more than a million simulated images showcasing the cosmos as NASA’s upcoming Nancy Grace Roman Space Telescope will see it. This preview will help scientists explore Roman’s myriad science goals. “We used a supercomputer to create a synthetic universe and simulated billions of years of evolution, tracing every photon’s path all the way from each cosmic object to Roman’s detectors,” said Michael Troxel, an associate professor of physics at Duke University in Durham, North Carolina, who led the simulation campaign. “This is the largest, deepest, most realistic synthetic survey of a mock universe available today.”

Ice Delays New Glenn Rocket Launch and Firefly Heads to the Moon

Blue Origin’s New Glenn rocket launch was pushed off again earlier today when ice was found building up on one of the lines related to the hydraulic systems.

At 3:09 a.m. EST, Blue Origin stated:

We’re standing down on today’s launch attempt to troubleshoot a vehicle subsystem issue that will take us beyond our launch window. We’re reviewing opportunities for our next launch attempt.

As a result, the new launch date is set for Thursday, January 16.

In the meantime, watch for the launch on Wednesday of Firefly Aerospace’s Blue Ghost Mission One as part of NASA’s Commercial Lunar Payload Services (CLPS) program. This mission will deliver 10 science and technology payloads to the Moon, including

  • testing regolith sample collection,
  • Global Navigation Satellite System abilities,
  • radiation tolerant computing, and
  • lunar dust mitigation. 

Firefly Aerospace notes:

Blue Ghost will spend approximately 45 days in transit to the Moon, allowing ample time to conduct health checks on each subsystem and begin payload science. Blue Ghost will then land in Mare Crisium and operate payloads for a complete lunar day (about 14 Earth days). Following payload operations, Blue Ghost will capture imagery of the lunar sunset and provide critical data on how lunar regolith reacts to solar influences during lunar dusk conditions. The lander will then operate for several hours into the lunar night.

Space Quote: Naming the First Space Shuttle

“NASA has received hundreds of thousands of letter from the space-oriented “Star Trek” group asking that the name “Enterprise” be given to the craft. This group comprises millions of individuals who are deeply interested in our space program.”

-Statement in a September 3, 1976 letter to President Richard Nixon from the Deputy Assistant to the President for Economic Affairs regarding the naming of the nation’s first space shuttle. If they space shuttle had been delayed until after 1977, maybe the “Millennium Falcon” would have been on the list of top names as well.

Universe TodayScientists Propose New Method to Detect Alien Civilizations via Black Holes

A new paper looks at another way we might be able to detect advanced civilizations, and at its center is the need for energy. The more advanced a civilization becomes, the greater their need for energy and one of the most efficient ways, according to current theories, is to harness the energy from an actively feeding black hole. The paper suggests a civilization feeding matter into a black hole could harvest energy from it; more excitingly perhaps, the process could be detectable within 17,000 light years.

LA TimesFirefighters Battle to Protect NASA’s Jet Propulsion Laboratory, Mt. Wilson

Officials said they are making progress in protecting two key institutions from the Eaton fire. Don Fregulia, an operations section chief for the California Department of Forestry and Fire Protection, which has joined in the Eaton fire response, said that efforts to protect Mt. Wilson had proved successful and he expected that to remain the case. “We’re actively engaged there, and so far, no loss to any values at risk at Mt. Wilson,” Fregulia said. “We’re feeling good about what we have to do up there tonight to keep that site secure.” He said the fire had also spread close to NASA’s Jet Propulsion Laboratory, but he said that’s a priority and crews were “making good progress there as well.”

NASANASA to Explore Two Landing Options for Returning Samples from Mars

To maximize chances of successfully bringing the first Martian rock and sediment samples to Earth for the benefit of humanity, NASA announced Tuesday a new approach to its Mars Sample Return Program. The agency will simultaneously pursue two landing architectures, or strategic plans, during formulation, encouraging competition and innovation, as well as cost and schedule savings. NASA plans to later select a single path forward for the program, which aims to better understand the mysteries of the universe, and to help determine whether the Red Planet ever hosted life. NASA is expected to confirm the program – and its design – in the second half of 2026.

Pic of the Week: Icelandic Volcanic Fissure

This week’s image comes from NASA’s Earth Observatory. It is an image from last November showing a volcanic fissure on Iceland’s Reykjanes peninsula not far from the country’s capital, Reykjavík

Here is more about the image from the NASA site:

The image…shows lava coming from an eruptive fissure near Stóra Skógfell peak, along the Sundhnúkur crater row—a similar location to the February 2024 eruption. This natural color scene, acquired by the OLI-2 (Operational Land Imager-2) on Landsat 9 on November 24, is overlaid with an infrared signal to help distinguish the lava’s heat signature. A plume of gas, consisting primarily of sulfur dioxide, streamed from the lava, although the eruption did not affect flights to and from Iceland.

The lava flowed east and west from the fissure, rather than toward the town of Grindavík. The Icelandic National Broadcasting Service reported that the latest event forced the evacuation of some of the town’s residents and the Blue Lagoon resort, a geothermal spa. A tongue of lava flowed over the car park of the spa, enveloping a small service building located there.

The Reykjanes peninsula eruption is the seventh in a series of events that began in December 2023. As of November 26, 2024, the Blue Lagoon was closed to the public, but lava movement toward the spa had slowed.

Note: Another image from NASA’s Earth Observatory is also very relevant this week. The image below shows the Los Angeles fires that are still burning. This particular image shows the Eaton fire, which erupted on the evening of January 7 in Altadena, located north of downtown Los Angeles.
