New research reveals how powerful coronal mass ejections may have been essential to the rise of life on planet Earth.

Quasiperiodic (QP) very low frequency (VLF) emissions are intermittent bursts of electromagnetic energy, observed in the frequency range of approximately 3–30 kHz, that recur at quasi-regular ...

How do you map something you can’t see? For astronomers studying the Milky Way, the answer lies in radio waves-the very lowest frequencies that slip past the dust and gas obscuring our galaxy’s heart.

An asteroid is the most likely reason the dinosaurs went extinct—but could something similar happen to us? A new study has compared the likelihood of a devastating asteroid impact to other causes of ...

The ternary composite (SiC/CoSi/CeSi) achieves an impressive RL value of -66.48 dB at 3.65 GHz, while maintaining 94.5% of its absorption performance (-63.34 dB at 4.31 GHz) even after oxidation at ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

At this time last year, the scientists working on Kepler, NASA’s fantastically successful planet-hunting space telescope, were ecstatic. The probe, launched in 2009, had originally been given just ...
