Did You Know That Only 313 Stars Have Officially Approved Names?

Did You Know That Only 313 Stars Have Officially Approved Names?

The cataloging of stars has seen a long history. Since prehistory, cultures and civilizations all around the world have given their own unique names to the brightest and most prominent stars in the night sky. Certain names have remained little changed as they passed through Greek, Latin, and Arabic cultures, and some are still in use today. As astronomy developed and advanced over the centuries, a need arose for a universal cataloging system, whereby the brightest stars were known by the same labels, regardless of the country or culture from which the astronomers came. This past year, the International Astronomical Union (IAU) formally approved 86 new names for stars and the IAU catalog now contains the officially approved names of 313 stars.

A New Twist in the Fantasy World of Dark Matter

A New Twist in the Fantasy World of Dark Matter

An innovative interpretation of X-ray data from a cluster of galaxies could help scientists fulfill the quixotic quest they have been on for decades -- determining the nature of dark matter. Dark matter is the mysterious invisible, and as of yet undetected, substance that many scientists believe makes up about 85 percent of the matter in the Universe. In 2014, astronomers reported the detection of an unusual emission line in X-ray light from the Perseus galaxy cluster. A new interpretation of this detection and follow-up observations may provide an explanation of this signal. If confirmed with future observations, this may represent a major step forward in understanding the nature of dark matter.

NASA's Juno Probes the Depths of Jupiter's Great Red Spot

NASA's Juno Probes the Depths of Jupiter's Great Red Spot

Data collected by NASA's Juno spacecraft during its first pass over Jupiter's Great Red Spot in July 2017 indicates that this iconic feature penetrates well below the clouds and has roots that go about 200 miles (300 kilometers) into the planet's atmosphere. The spacecraft also detected a new radiation zone just above the gas giant's atmosphere, near the equator. The zone includes energetic hydrogen, oxygen, and sulfur ions moving at almost light speed.

Night-Sky Light Pollution -- Satellite Imagery Confirms What We Already Know

Night-Sky Light Pollution -- Satellite Imagery Confirms What We Already Know

Five years of advanced satellite images show that there is more artificial light at night across the globe... And that light at night is getting brighter. The rate of growth is approximately two percent each year in both the amount of areas lit and in the radiance of the light. As streetlights the world over change from sodium lamps to LEDs, scientists wonder what this means for night skies. Scientists are finding that much of the financial savings derived from the improved energy efficiency of outdoor lighting is being wasted in the deployment of more lights. As a result, the projected large reduction in global energy consumption for outdoor lighting is not being realized.

It Came From Outer Space -- Astronomers Find First Interstellar Asteroid

Astronomers recently scrambled to observe an intriguing asteroid that zipped through the Solar System on a steep trajectory from interstellar space -- the first confirmed object from another star. Now, new data reveals the interstellar interloper to be a rocky, cigar shaped object with a somewhat reddish hue. The asteroid, named Oumuamua by its discoverers, is up to one quarter mile (400 meters) long and highly elongated -- perhaps 10 times as long as it is wide. While its elongated shape is quite surprising and unlike asteroids seen in our Solar System, it may provide new clues into how other star systems formed.

Have the Imaginary Concepts of Dark Matter and Dark Energy Finally Run Their Course?

Have the Imaginary Concepts of Dark Matter and Dark Energy Finally Run Their Course?

A University of Geneva researcher has shown that the accelerating expansion of the Universe and the movement of the stars in galaxies can be explained without drawing on the concepts of Dark Matter and Dark Energy... And the work is pointing to a very inconvenient conclusion -- These two entities may not actually exist. History provides us with many examples where scientists have simply invented ideas out of thin air to help explain away things that are just not understood. In some ways, Dark Matter and Dark Energy bring to mind another imaginary concept -- the so called "Aether Wind." In 1887, Albert Michelson and Edward Morley proved that there was no such thing, even though everybody just "knew" that space was filled with it. Will this new work lead to the development of a Michelson-Morley-like experiment for the 21st century that does away with the concepts of Dark Matter and Dark Energy? Time will tell.

Physicists Describe New Dark Matter Detection Strategy

Physicists Describe New Dark Matter Detection Strategy

Though it has not yet been detected directly, physicists are fairly certain that dark matter must exist in some form. The way in which galaxies rotate and the degree to which light bends as it travels through the universe suggest that there's some kind of unseen stuff throwing its gravity around. The leading idea for the nature of dark matter is that it's some kind of particle, albeit one that interacts very rarely with ordinary matter. But nobody is quite sure what a dark matter particle's properties might be because nobody has yet recorded one of those rare interactions. Physicists from Brown University have now devised a new strategy for directly detecting dark matter.

Space Launch System (Saturn V on Steroids) to Fly December 2019

 Space Launch System (Saturn V on Steroids) to Fly December 2019

NASA has provided an update on the first integrated launch of the Space Launch System (SLS) rocket and Orion spacecraft after completing a comprehensive review of the launch schedule. This first un-crewed mission, known as Exploration Mission-1 (EM-1) is a critical flight test for NASA's human deep space exploration goals. EM-1 lays the foundation for the first crewed flight of SLS and Orion, as well as a regular cadence of missions thereafter near the Moon and eventually to the asteroids and Mars. NASA is currently managing the program to a scheduled December 2019 launch.

First Time That a Cosmic Event is Observed Optically and With Gravitational Waves

First Time That a Cosmic Event is Observed Optically and With Gravitational Waves

For the first time, scientists have directly detected gravitational waves (ripples in space-time) together with the light from a spectacular collision of two neutron stars. This marks the first time that a cosmic event has been observed with both gravitational waves and light. The discovery was made using the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US, the Virgo detector in Italy, and some 70 ground and space-based observatories. As two neutron stars spiraled together about 130 million years ago, they emitted gravitational waves that were detected for about 100 seconds on August 17, 2017. In the days and weeks following the initial discovery, a full spectrum of light and electromagnetic radiation from the event (including X-ray, ultraviolet (UV), optical, infrared (IR) and radio waves) were detected and analyzed -- A treasure trove of material that will keep scientist busy for years to come.

US Geological Survey Speculates -- What's in the Yellowstone Super Volcano's Future?

US Geological Survey Speculates -- What's in the Yellowstone Super Volcano's Future?

Yellowstone, one of the world's largest active volcanic systems, has produced several giant volcanic eruptions in the past few million years, as well as many smaller eruptions and steam explosions. Although no eruptions of lava or volcanic ash have occurred for many thousands of years, future eruptions are likely. In the next few hundred years, hazards will most probably be limited to ongoing geyser and hot spring activity, with occasional steam explosions and moderate to large earthquakes. To better understand Yellowstone's volcano and earthquake hazards and to help protect the public, the US Geological Survey, the University of Utah, and Yellowstone National Park formed the Yellowstone Volcano Observatory, which continuously monitors activity in the region.
