Gravitational Smearing

Gravitational Smearing

Purported galaxy SPT0615-JD. Image credit: NASA/ESA/STScI/B. Salmon. Jan 17, 2019 Can strong gravity bend space? Einstein's theory of General Relativity states that, when light passes close to a massive celestial object it bends in the same way that light is refracted by a glass lens. In consensus circles, that phenomenon ...

Electromagnetic Stars

Electromagnetic Stars

A composite image of SGR 1900+14 from the Spitzer Space Telescope. Blue represents 8-micron infrared light, green is 16-micron light and red is 24-micron light. Jan 16, 2019 What are magnetars? As conventional understanding suggests, neutron stars are created when massive stars collapse at the end of their life cycles ...

Frostbite

Frostbite

A cross-section through what is thought to be underground ice on Mars. Credit: NASA/JPL-Caltech/UA/USGS. Jan 15, 2019 Does water ice exist on Mars? "He who cannot put his thoughts on ice should not enter into the heat of dispute."--- Friedrich Nietzsche Mars is mysterious. Although it is the most extensively ...

Alpha, Beta, Gamma

Alpha, Beta, Gamma

The gamma-ray sky constructed from 6.5 years of 1–6.5 GeV data from the Fermi-LAT telescope. Colors indicate the strength of the gamma-ray emission, from low (black) to high (yellow). Credit: Fermi-LAT. Jan 14, 2019 Gamma-rays from electric particle accelerators in space. Gamma-rays are the highest energy wavelength in the electromagnetic spectrum, according ...

Shake, Rattle and Roll

The Seismic Experiment for Interior Structure seismometer now on Mars. Credit: NASA/JPL-Caltech. Jan 11, 2019 Do marsquakes exist? NASA launched the InSight Mars lander from Vandenberg Air Force Base on May 5, 2018. The mission's primary focus is the detection of marsquakes. In the image at the top of the ...

Double Layer Manifestation

Double Layer Manifestation

Double layers surrounding a discharge electrode. Credit: SAFIRE project. Jan 10, 2019 Electric fields in space generate cosmic phenomena. Astronomers discovered an energy signature they called a “Fast Radio Burst”, or FRB, almost ten years ago. The event supposedly released more energy in five milliseconds than the Sun puts out ...

Plasma Filaments

Plasma Filaments

NGC 4696 reveals a cloud of plasma (red) around voids 10,000 light years across (blue). Green dots are the infrared emissions from star clusters on the outer edges of the galaxy. Jan 9, 2019 Plasma is electrically ionized. In plasmas, thermal and other energy sources strip electrons from atomic nuclei ...

Methane Lakes on Titan?

Methane Lakes on Titan?

Artist's impression of Titan based on Cassini radar and data from the Huygens lander. The relative elevations are speculative, based on the assumption that liquid is flowing downhill. Credit: NASA/JPL/ESA/SSI and M. Malaska/B. Jonsson. Click to enlarge. Jan 8, 2019 No precipitation of any kind was detected on Titan. The ...

Stereo anaglyph of Ultima Thule. Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute. Jan 7, 2019 New Horizons recently flew by the most distant object imaged by any spacecraft. The Kuiper Belt theory is the creation of astronomer Kenneth Edgeworth from Ireland and also, separately, by American astronomer Gerard ...

Star Formation and the Electric Universe

Star Formation and the Electric Universe

ALMA views of IRAS 04368+2557. According to a recent press release, astronomers detected a warped dust ring around a presumed protoplanetary disk in the Taurus Molecular Cloud, located about 450 light years away. A previous Picture of the Day discussed the warped ring of material surrounding the nucleus of Galaxy ...

Electric Earth

Electric Earth

Jan 3, 2019 All celestial bodies exhibit electrical activity, including Earth. NASA launched the four Magnetospheric Multiscale Satellites on March 12, 2015. Their primary mission includes studying the magnetic field around Earth, especially what mainstream astrophysicists call “magnetic reconnection”. The theory states that electromagnetic fields can break, cross and then ...

Electrical Giant

Electrical Giant

Jan 2, 2019 Jupiter is electrodynamic. Many Pictures of the Day discuss the planet, Jupiter—especially its electromagnetic interaction with its moons and the rest of the Solar System. Jupiter’s magnetosphere extends for almost 650 million kilometers; even beyond Saturn’s orbit. Bands of radiation, similar to the Van Allen radiation belts, except thousands of ...

Starquakes?

Starquakes?

Jan 5, 2018 Shockwaves do not drive stellar evolution and behavior. NASA launched the Kepler mission on March 6, 2009. Its goal was to hunt for planets around nearby stars. Kepler subsequently experienced a failure in its stabilizing mechanism, making it unable to maintain its position accurately enough for planet-hunting, so its systems were repurposed ...
