Black Hole Jet Stumbles Into Something in the Dark
- Astronomers have discovered an unusual mark from a giant black hole's powerful jet striking an unidentified object in its path in a galaxy called Centaurus A.
- Using NASA's Chandra X-ray Observatory, the jet is found to be moving at close to the speed of light in certain spots.
- They also found a patch of V-shaped emission connected to a bright source of X-rays, something that had not been seen before in this galaxy and called C4.
- C4 is located close to the path of the jet from the black hole and is found to have at least about 700 light-years long arms.
- Researchers believe that C4 could be a massive star, either by itself or with a companion star.
- The X-rays from C4 could be caused by the collision between the particles in the jet and the gas in a wind blowing away from the star.
- A paper describing these results appears in a recent issue of The Astrophysical Journal.
- Chandra is the only X-ray observatory capable of seeing this feature.
- This is not the first time astronomers have seen a black hole jet running into other objects in Cen A.
- Astronomers are trying to determine why C4 has this different post-contact appearance, but it could be related to the type of object that the jet is striking or how directly the jet is striking it.

NASA Scientific Balloon Flights to Lift Off From Antarctica
- NASA’s Scientific Balloon Program has kicked off its annual Antarctic Long-Duration Balloon Campaign, where two balloon flights will carry a total of nine missions to near space, including investigations in astrophysics, space biology, heliospheric research and upper atmospheric research, along with technology demonstrations.
- The campaign includes a General Anti-Particle Spectrometer experiment designed to detect anti-matter particles, a good indication of dark matter interactions.
- The second mission, Salter Test Flight Universal, will test and validate long-duration balloon and subsystems, while supporting several piggyback missions.
- Piggyback missions include a U.S. Naval Research Laboratory experiment exposing fungus to the stratosphere’s extreme radiation and temperature fluctuations, National Polytechnical Institute’s technological platform with experimental design and operational validation of instrumentation that will collect and store data from the stratospheric environment to contribute to the study of climate change among others.
- NASA’s zero-pressure balloons, used in the Antarctic campaign, are capable of lifting up to 8,000 pounds of payload and equipment to altitudes above 99.8% of Earth’s atmosphere.
- Zero-pressure balloons can support long-duration missions in polar regions during summer and can remain in near space for days to weeks.
- NASA's Scientific Balloon Program is funded by the NASA Headquarters Science Mission Directorate Astrophysics Division.
- The program is managed by NASA’s Wallops Flight Facility, with support provided by the U.S. National Science Foundation, New Zealand and the U.S. Air Force.
- The constant daylight of Antarctica’s summer and stable stratospheric wind conditions allow the balloon missions to circle the continent.
- NASA balloons are fabricated by Aerostar and launched by the Columbia Scientific Balloon Facility, which has launched over 1,700 scientific balloons over some 40 years of operations.

Discovery Alert: A Planet with a ‘Tail’
- The exoplanet WASP-69 b has a 'tail,' leaving a trail of gas in its wake.
- WASP-69 b is slowly losing its atmosphere as light hydrogen and helium particles escape unevenly around the planet, forming a tail of gas swept by the stellar wind.
- The tail extends more than 7.5 times the radius of the planet and could be an indicator of stellar behavior over time.
- WASP-69 b is losing about 200,000 tons of gas per second, but its atmosphere loss is very slow, equivalent to losing the mass of planet Earth every billion years.

High Velocity Clouds Comprise Less of the Milky Way’s Mass Than We Thought
- High-velocity clouds (HVCs) in the Milky Way's halo were believed to comprise a significant amount of baryonic matter.
- A study using data from the Galactic All Sky Survey (GASS) estimates that HVCs actually make up an insignificant fraction of the galaxy's baryonic mass.
- Previous observations suggested up to 10% of the halo baryonic mass could be due to HVCs, but the new estimation is closer to 0.1%.
- Further radio surveys are needed to improve the accuracy of HVC distances and obtain a more precise value.

Scientists Share Early Results from NASA’s Solar Eclipse Experiments
- On April 8, 2024, a total solar eclipse swept across North America, from the western shores of Mexico, through the United States, and into northeastern Canada.
- On dec. 10 in Washington, D.C., scientists attending the annual meeting of the American Geophysical Union reported some early results from a few of these eclipse experiments.
- The Citizen CATE 2024 project stationed 35 observing teams to capture images of the Sun’s outer atmosphere during totality.
- On board were cameras which captured detailed images of the corona, and the spectrometers, which were located in the nose of the aircraft, were not affected.
- Radio communications inside and outside the path of totality improved at some frequencies, showing there was a reduction in ionospheric absorption. At higher frequencies, communications worsened.
- This research, conducted by over 800 students, confirmed that eclipses can generate ripples in Earth’s atmosphere called atmospheric gravity waves.
- Scientists think the trigger for these waves is a “hiccup” in the tropopause, a layer in Earth’s atmosphere, similar to an atmospheric effect that is observed during sunset.
- Their goal is to see how the corona changed as totality swept across the continent.
- Scientists are already planning to fly similar experiments on the aircraft again.
- Their efforts were a crucial part of the Heliophysics Big Year – helping us to learn more about the Sun and how it affects Earth’s atmosphere when our star’s light temporarily disappears from view.
