Hubble's NGC 1546

 

Returning to science operations on June 14, the Hubble Space Telescope used its new pointing mode to capture this sharp image of spiral galaxy NGC 1546. A member of the Dorado galaxy group, the island universe lies a mere 50 million light-years away. The galactic disk of NGC 1546 is tilted to our line-of-sight, with the yellowish light of the old stars and bluish regions of newly formed stars shining through the galaxy's dust lanes. More distant background galaxies are scattered throughout this Hubble view. Launched in 1990, Hubble has been exploring the cosmos for more than three decades, recently celebrating its 34th anniversary.

NASA Releases Updated Climate Change Adaptation, Resilience Plan

JUN 20, 2024

 

NASA joined more than 20 federal agencies in releasing its updated Climate Adaptation Plan Thursday, helping expand the Biden-Harris Administration’s efforts to make federal operations increasingly resilient to the impacts of climate change for the benefit of all.

 

The updated plans advance the administration’s National Climate Resilience Framework, which helps align climate resilience investments across the public and private sectors through common principles and opportunities.

 

“Thanks to the leadership of the Biden-Harris Administration, we are strengthening climate resilience to ensure humanity is well-prepared for the effects of climate change,” said NASA Administrator Bill Nelson. “NASA’s decades of Earth observation are key to building climate resiliency and sustainability across the country and the world.”

 

NASA serves as a global leader in Earth science, providing researchers with crucial data from its satellites and other assets, as well as other observations and research on the climate system.

The agency also works to apply that knowledge and inform the public about climate change. NASA will continue to prioritize these efforts and maintain an open information policy that makes its science data, software, and research freely available to all.

 

Climate variability and change also have potential impacts on NASA’s ability to fulfill its mission, requiring proactive planning and action from the agency.

To ensure coastal flooding, extreme weather events, and other climate change impacts do not stop the agency’s work, NASA is improving its climate hazard analyses and developing plans to protect key resources and facilities.

 

“As communities face extreme heat, natural disasters and severe weather from the impacts of climate change, President Biden is delivering record resources to build climate resilience across the country,” said Brenda Mallory, chair of the White House Council on Environmental Quality.

“Through his Investing in America agenda and an all-of-government approach to tackling the climate crisis, the Biden-Harris Administration is delivering more than $50 billion to help communities increase their resilience and bolster protections for those who need it most. By updating our own adaptation strategies, the federal government is leading by example to build a more resilient future for all.”

 

At the beginning of his administration, President Biden tasked federal agencies with leading whole-of-government efforts to address climate change through Executive Order 14008, Tackling the Climate Crisis at Home and Abroad.

Following the magnitude of challenges posed by the climate crisis underscored last year when the nation endured a record 28 individual billion-dollar extreme weather and climate disasters that caused more than $90 billion in aggregate damage, NASA continues to be a leader and partner in adaptation and resilience.

 

NASA released its initial Climate Adaptation Plan in 2021 and progress reports outlining advancements toward achieving their adaptation goals in 2022.

In coordination with the White House Council on Environmental Quality and the Office of Management and Budget, agencies updated their Climate Adaptation Plans for 2024 to 2027 to better integrate climate risk across their mission, operations, and asset management, including:

 

Combining historical data and projections to assess exposure of assets to climate-related hazards including extreme heat and precipitation, sea level rise, flooding, and wildfire.

Expanding the operational focus on managing climate risk to facilities and supply chains to include federal employees and federal lands and waters.

Broadening the mission focus to describe mainstreaming adaptation into agency policies, programs, planning, budget formulation, and external funding.

Linking climate adaptation actions with other Biden-Harris Administration priorities, including advancing environmental justice and the President’s Justice40 Initiative, strengthening engagement with Tribal Nations, supporting the America the Beautiful initiative, scaling up nature-based solutions, and addressing the causes of climate change through climate mitigation.

Adopting common progress indicators across agencies to assess the progress of agency climate adaptation efforts.

 

All plans from each of the more than 20 agencies and more information are available online.

NASA’s Hubble Celebrates 21st Anniversary with “Rose” of Galaxies

JUN 20, 2024

 

To celebrate the 21st anniversary of the Hubble Space Telescope’s deployment into space, astronomers at the Space Telescope Science Institute in Baltimore, Md., pointed Hubble’s eye at an especially photogenic pair of interacting galaxies called Arp 273.

The larger of the spiral galaxies, known as UGC 1810, has a disk that is distorted into a rose-like shape by the gravitational tidal pull of the companion galaxy below it, known as UGC 1813.

This image is a composite of Hubble Wide Field Camera 3 data taken on December 17, 2010, with three separate filters that allow a broad range of wavelengths covering the ultraviolet, blue, and red portions of the spectrum.

NASA’s Chandra Peers Into Densest and Weirdest Stars

JUN 20, 2024

 

The supernova remnant 3C 58 contains a spinning neutron star, known as PSR J0205+6449, at its center. Astronomers studied this neutron star and others like it to probe the nature of matter inside these very dense objects. A new study, made using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton, reveals that the interiors of neutron stars may contain a type of ultra-dense matter not found anywhere else in the Universe.

 

In this image of 3C 58, low-energy X-rays are colored red, medium-energy X-rays are green, and the high-energy band of X-rays is shown in blue. The X-ray data have been combined with an optical image in yellow from the Digitized Sky Survey. The Chandra data show that the rapidly rotating neutron star (also known as a “pulsar”) at the center is surrounded by a torus of X-ray emission and a jet that extends for several light-years. The optical data shows stars in the field.

 

The team in this new study analyzed previously released data from neutron stars to determine the so-called equation of state. This refers to the basic properties of the neutron stars including the pressures and temperatures in different parts of their interiors.

 

The authors used machine learning, a type of artificial intelligence, to compare the data to different equations of state. Their results imply that a significant fraction of the equations of state — the ones that do not include the capability for rapid cooling at higher masses — can be ruled out.

 

The researchers capitalized on some neutron stars in the study being located in supernova remnants, including 3C 58. Since astronomers have age estimates of the supernova remnants, they also have the ages of the neutron stars that were created during the explosions that created both the remnants and the neutron stars. The astronomers found that the neutron star in 3C 58 and two others were much cooler than the rest of the neutron stars in the study.

 

The team thinks that part of the explanation for the rapid cooling is that these neutron stars are more massive than most of the rest. Because more massive neutron stars have more particles, special processes that cause neutron stars to cool more rapidly might be triggered.

 

One possibility for what is inside these neutron stars is a type of radioactive decay near their centers where neutrinos — low mass particles that easily travel through matter — carry away much of the energy and heat, causing rapid cooling.

Another possibility is that there are types of exotic matter found in the centers of these more rapidly cooling neutron stars.

Japan space agency suffers multiple cyberattacks since last year

Updated on June 21, 2024 16:22 JST

 

Japan's space agency has been hit by multiple cyberattacks since last year, the government said Friday, with a potential data leak suspected, but the science ministry says no confidential information leak has been confirmed.

A source close to the matter said the cyberattacks are believed to have been perpetrated by Chinese-affiliated hackers, adding a huge number of files may have been viewed, including information on external companies and organizations under nondisclosure agreements with the Japan Aerospace Exploration Agency.

 

JAXA said the network that was accessed illegally did not contain "sensitive information" related to the operations of rockets, satellites and national security.

Japanese science minister Masahito Moriyama said there is "no great concern."

Chief Cabinet Secretary Yoshimasa Hayashi, the top government spokesman, said at a regular press conference that JAXA is investigating the incidents to determine their impact with the cooperation of specialized organizations.

 

The server attacked in June 2023 stored personal data of JAXA employees, which might have been used to gain access to classified documents, the source said.

The attackers apparently exploited a vulnerability in the virtual private network that allows external connection to the internal system.

JAXA has suffered several cyberattacks this year, according to the source.

The agency was also targeted by cyberattacks in 2016 and 2017, which appeared to be aimed at data theft by hackers affiliated with China.
