The corona is weirdly hot: Parker Solar Probe rules out one explanation

Science Daily - Tue, 07/30/2024 - 1:47pm
By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures.

NASA's Fermi finds new feature in brightest gamma-ray burst yet seen

Science Daily - Thu, 07/25/2024 - 4:54pm
In October 2022, astronomers were stunned by what was quickly dubbed the BOAT -- the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA's Fermi Gamma-ray Space Telescope reveals a feature never seen before.

Dark matter flies ahead of normal matter in mega galaxy cluster collision

Science Daily - Wed, 07/24/2024 - 5:15pm
Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter.

Images of nearest 'super-Jupiter' open a new window to exoplanet research

Science Daily - Wed, 07/24/2024 - 12:30pm
Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.

Expiring medications could pose challenge on long space missions

A new study shows that over half of the medicines stocked in space -- staples such as pain relievers, antibiotics, allergy medicines, and sleep aids -- would expire before astronauts could return to Earth.

Astrophysicists uncover supermassive blackhole/dark matter connection in solving the 'final parsec problem'

Science Daily - Mon, 07/22/2024 - 5:59pm
Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding 'final parsec problem' in astronomy.

Life signs could survive near surfaces of Enceladus and Europa

Science Daily - Sun, 07/21/2024 - 11:32am
Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.

Early riser! The Sun is already starting its next solar cycle -- despite being halfway through its current one

Science Daily - Fri, 07/19/2024 - 12:38pm
The first rumblings of the Sun's next 11-year solar cycle have been detected in sound waves inside our home star -- even though it is only halfway through its current one. This existing cycle is now at its peak, or 'solar maximum' -- which is when the Sun's magnetic field flips and its poles swap places -- until mid-2025.
