Astrophysicists create the most accurate ‘flat map’ of Earth ever

Earth is a sphere, so how can it be accurately portrayed on a 2D map? Simply flatten Earth into two pancakes, one depicting the Northern Hemisphere and the other the Southern, with the equator running around the edge, a new study finds. These two “pancakes” represent the most accurate flat map of Earth ever made, […]

First 3D Sound-Frequency Map for Inner Ear Created With Advanced X-ray Technology

Ear membrane and auditory nerve in the cochlea. The octave bands have been given different colors. Humans can perceive frequencies from 20 Hz (the top of the coil) to 20,000 Hz (the base of the coil). The image also shows the round window, the oval window where sound enters and the facial nerve.

A map of 25,000 Supermassive Black Holes Across the Universe

The Low-Frequency Array (LOFAR) is a different kind of radio telescope. Although radio light has the longest wavelengths and lowest frequencies of the electromagnetic spectrum, much of radio astronomy has focused on the higher frequency end. Observatories such as ALMA study radio light at frequencies of hundreds of Gigahertz, and the VLA studies the fifty […]

NASA’s Unprecedented Map of Sun’s Magnetic Field – Including the Mysterious Chromosphere

The chromosphere, photographed during the 1999 total solar eclipse. The red and pink hues – light emitted by hydrogen – earned it the name chromosphere, from the Greek “chrôma” meaning color. Credit: Luc Viatour For decades after its discovery, observers could only see the solar chromosphere for a few fleeting moments: during a total solar […]

New Map of Solar Neighborhood Reveals That Binary Stars Are All Around Us

Gaia survey provides location and motion of 1.3 million binary pairs within 3,000 light years of Earth. The latest star data from the Gaia space observatory has for the first time allowed astronomers to generate a massive 3D atlas of widely separated binary stars within about 3,000 light years of Earth — 1.3 million of […]

Unprecedented Map of the Sun’s Magnetic Field Created by CLASP2 Space Experiment

Artistic visualization of the Sun’s magnetic field in the active region observed by CLASP2. Credit: Gabriel Pérez Díaz, SMM (IAC) Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the outer layers of the solar atmosphere, where the explosive events […]
