Gum 41, a radiant nebula in the southern sky, glows due to powerful radiation from a pair of massive stars at its core. This ...

In a paper published earlier this month in Physical Review Letters, a team of physicists led by Jonathan Richardson of the ...

As the most intense star-forming region in the Local Group, 30 Doradus is of particular importance to astronomers.

The research paper reports a breakthrough that will enable gravitational-wave detectors to reach extreme laser powers. It ...

Scientists have discovered that gravitational waves could turn neutron stars into cosmic tuning forks with characteristic reverberations that reveal their interiors.

Radiotherapy, or radiation therapy, is the clinical use of high energy rays (ionizing radiation) to induce DNA damage in all exposed cells to ultimately kill cancer cells or prevent cancer growth.

Again last week Dr. Robert Andrews Millikan reiterated that the universe is constantly being regenerated. Sir James Hopwood Jeans, and others, argue that it is blowing into wavy smithereens.

Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

Elementary particles were created. And, eventually, the cosmic flash dance left behind scars in the fabric of space-time. Physicists call them cosmic strings. Like stretch marks left on skin that ...

Chorus waves are a type of electromagnetic radiation that travels along Earth's magnetic field lines. When converted into sound, their rising frequencies mimic the high-pitched trills of birds.

(NASA via AP) NEW YORK (AP) — Scientists have detected cosmic waves that sound like birds chirping ... And twin spacecraft — NASA’s Van Allen Probes — heard the chirps from Earth’s radiation belts at ...
