NASA astronauts Peggy Whitson and Jack Fischer live-streamed a broadcast from space today using 4K ultra-high-definition technology for the first time. The duo called down to the National Association of Broadcasters in Las Vegas to demonstrate the advanced technology and promote space science and filmmaking.
Expedition 51 worked throughout Wednesday on a variety of microgravity research and spaceship unpacking. The five crew members also conducted vision checks while their newest pair continu [...]
Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, however, because its star is so faint. But the discovery adds to scientists' understanding of the types of planetary systems that exist beyond our own.
"This 'iceball' planet is the lowest-mass planet ever found through microlensing," said Yossi Shvartzvald, a NASA postdoctoral fellow based at N [...]
Mt. Etna has been erupting for hundreds of thousands of years. Located in Sicily, Italy, the volcano produces lava fountains over one kilometer high. Mt. Etna is not only one of the most active volcanoes on Earth, it is one of the largest, measuring over 50 kilometers at its base and rising nearly 3 kilometers high.
Pictured in mid-March, a spectacular lava plume erupts upwards, dangerous molten volcanic bombs fly off to the sides, while hot lava flows down the volcano's exterior. The Earth' [...]
What's happened to Comet Lovejoy? In the pictured image, a processed composite, the comet was captured early this month after brightening unexpectedly and sporting a long and intricate ion tail. Remarkably, the typically complex effect of the Sun's wind and magnetic field here caused the middle of Comet Lovejoy's ion tail to resemble the head of a needle. Comet C/2017 E4 (Lovejoy) was discovered only last month by noted comet discoverer Terry Lovejoy.
The comet reached visual magnitude 7 ear [...]
Expedition 51 Commander Peggy Whitson broke the U.S. record today for most cumulative time living in space, surpassing astronaut Jeff Williams’ record of 534 days set during his four spaceflights. She passed Williams’ mark at 1:27 a.m. EDT.
President Donald Trump called the International Space Station Monday morning and congratulated Whitson on her record-breaking career. Whitson and her newest crewmate NASA astronaut Jack Fischer discussed NASA’s research in space and its plans to go t [...]
Trillions have died in the Earth's seas. Calcified shields of the dead already make up the white cliffs of Dover. The battle between ball-shaped light-colored single-celled plants -- phytoplankton called coccolithophores -- and even smaller, diamond-shaped viruses dubbed coccolithoviruses -- has raged for tens of millions of years. To help fight this battle, the coccolithophores create their chalky armor by absorbing carbon dioxide from the atmosphere.
This battle is so epic that coccolithop [...]

Robert Walker is an inventor & programmer for Tune Smithy, Bounce Metronome, Virtual flower, Lissajous 3D, and Activity Timer. I trained as a mathematician originally. Went on to study philosophy then to do post graduate research into set theory [...]
Is this picture worth a thousand words? According to the Holographic Principle, the most information you can get from this image is about 3 x 1065 bits for a normal sized computer monitor. The Holographic Principle, yet unproven, states that there is a maximum amount of information content held by regions adjacent to any surface. Therefore, counter-intuitively, the information content inside a room depends not on the volume of the room but on the area of the bounding walls.
The principle der [...]
The Orbital ATK Cygnus cargo ship was bolted into place on the International Space Station’s Earth-facing port of the Unity module at 8:39 a.m. EDT. Crew will ingress the spacecraft later today. The spacecraft will spend about three months on station before it is released in July for a destructive re-entry into the Earth’s atmosphere, disposing of several thousand pounds of trash.
The spacecraft’s arrival brings more than 7,600 pounds of research and supplies to support Expedition 51 an [...]
On April 12, as the Sun was blocked by the disk of Saturn the Cassini spacecraft camera looked toward the inner Solar System and the gas giant's backlit rings. At the top of the mosaicked view is the A ring with its broader Encke and narrower Keeler gaps visible. At the bottom is the F ring, bright due to the viewing geometry. The point of light between the rings is Earth, 1.4 billion kilometers in the distance.
Look carefully and you can even spot Earth's large moon, a pinprick of light to [...]
An Orbital ATK Cygnus spacecraft carrying more than 7,600 pounds of supplies, science and research investigations is set to arrive to the International Space Station early Saturday morning. The uncrewed cargo ship launched at 11:11 a.m. EDT on Tuesday, April 18 on a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida to begin its four-day journey to the orbiting laboratory.

Seen edge-on, spiral galaxy NGC 4302 (left) lies about 55 million light-years away in the well-groomed constellation Coma Berenices. A member of the large Virgo Galaxy Cluster, it spans some 87,000 light-years, a little smaller than our own Milky Way. Like the Milky Way, NGC 4302's prominent dust lanes cut along the center of the galactic plane, obscuring and reddening the starlight from our perspective. Smaller companion galaxy NGC 4298 is also a dusty spiral.
But tilted more nearly face-on [...]
Two new crew members are aboard the International Space Station. The hatches on the space station and Soyuz MS-04 opened at 11:25 a.m. EDT, marking the arrival to the orbiting laboratory for NASA astronaut Jack Fischer and Fyodor Yurchikhin of the Russian space agency Roscosmos.
Along with Expedition 51 Commander Peggy Whitson of NASA and Flight Engineers Oleg Novitskiy of Roscosmos and Thomas Pesquet of ESA (European Space Agency), the arriving crew members will contribute to more than 250 r [...]
A day before its closest approach, asteroid 2014 JO25 was imaged by radar with the 70-meter antenna of NASA's Goldstone Deep Space Communications Complex in California. This grid of 30 radar images, top left to lower right, reveals the two-lobed shape of the asteroid that rotates about once every five hours. Its largest lobe is about 610 meters across.
On the list of Potentially Hazardous Asteroids, this space rock made its close approach to our fair planet on April 19, flying safely past at [...]
As NASA's Dawn spacecraft continues exploring Ceres, evidence mounts that the enigmatic dwarf planet retains a significant amount of water ice. A new study in the journal Nature Geoscience adds to this picture, showing how ice may have shaped the variety of landslides seen on Ceres today.
"Images from Dawn show that landslides, many of which are similar to those seen on Earth, are very common on Ceres, and further the case that Ceres has a lot of water ice involved in its structure," said Bri [...]
Two Expedition 51 crew members are in quarantine today at the Cosmonaut Hotel in Baikonur, Kazakhstan, getting ready for their liftoff Thursday morning. Meanwhile, new science gear and crew supplies are on orbit right now and headed for the International Space Station this weekend.

Transiting rocky super-Earth found in habitable zone of quiet red dwarf star.
An exoplanet orbiting a red dwarf star 40 light-years from Earth may be the new holder of the title “best place to look for signs of life beyond the Solar System”. Using ESO’s HARPS instrument at La Silla, and other telescopes around the world, an international team of astronomers discovered a “super-Earth” orbiting in the habitable zone around the faint star LHS 1140. This world is a little larger and muc [...]
Oh what a tangled web a planetary nebula can weave. The Red Spider Planetary Nebula shows the complex structure that can result when a normal star ejects its outer gases and becomes a white dwarf star. Officially tagged NGC 6537, this two-lobed symmetric planetary nebula houses one of the hottest white dwarfs ever observed, probably as part of a binary star system.
Internal winds emanating from the central stars, visible in the center, have been measured in excess of 1000 kilometers per seco [...]
