"Hundreds of millions of pieces of space junk orbit the Earth daily, from chips of old rocket paint, to shards of solar panels, and entire dead satellites. This cloud of high-tech detritus whirls around the planet at about 17,500 miles per hour. At these speeds, even trash as small as a pebble can torpedo a passing spacecraft.

NASA and the U.S. Department of Defense are using ground-based telescopes and laser radars (ladars) to track more than 17,000 orbital debris objects to help prevent collisions with operating missions. Such ladars shine high-powered lasers at target objects, measuring the time it takes for the laser pulse to return to Earth, to pinpoint debris in the sky."

A NASA suborbital sounding rocket carrying multiple student experiments was successfully launched at 5:30 a.m. EDT, Thursday, June 22, from the Wallops Flight Facility in Virginia.

The mission carried experiments built by undergraduate students from universities and community colleges across the country through the RockOn! and RockSat-C programs.

The experiments, launch on a 36-foot long Terrier-Improved Orion sounding rocket, flew to an altitude of 72 miles and landed, via parachute, in the Atlantic Ocean. The payload has been recovered and the students are expected to receive their experiments this afternoon to begin their data analysis. Read more: https://go.nasa.gov/2rHb0oQ

Exploring the Orion Nebula in infrared light for an upcoming project. This view, from the WISE mission, clearly shows the "bowl" carved by the stars of the trapezium. It also shows how the cool gas underlies the nebula and connects between Orion and the Running Man Nebula above it. It also extends down along a dense filament of cold gas that is dark at visible wavelengths. Multi-wavelength astronomy shows us diverse views that teach us so much more about the universe.

NASA's Webb Telescope "chilling out" in Houston for the summer

NASA’s James Webb Space Telescope was placed in Johnson Space Center’s historic Chamber A on June 20, 2017, to prepare for its final three months of testing in a cryogenic vacuum that mimics temperatures in space.

Engineers will perform the test to prove that the telescope can operate in space at these temperatures. Chamber A will simulate an environment where the telescope will experience extreme cold -- around 37 Kelvin (minus 236 degrees Celsius or minus 393 degrees Fahrenheit).

In space, the telescope must be kept extremely cold, in order to be able to detect the infrared light from very faint, distant objects.

In space, the telescope must be kept extremely cold, in order to be able to detect the infrared light from very faint, distant objects. To protect the telescope from external sources of light and heat (like the sun, Earth, and moon), as well as from heat emitted by the observatory, a five-layer, tennis court-sized sunshield acts like a parasol that provides shade. The sunshield separates the observatory into a warm, sun-facing side (reaching temperatures close to 400 degrees Fahrenheit) and a cold side (185 degrees below zero). The sunshield blocks sunlight from interfering with the sensitive telescope instruments. Read more: https://go.nasa.gov/2sZAilS___

“The huge advance of LISA, though, will be the ability to detect objects spiraling into and merging with the supermassive black holes at the centers of galaxies. Stars and other forms of matter are constantly falling into black holes at the galactic center, both in our own galaxy and well beyond. These events often result in the ejection of matter, the acceleration of charged particles and the emission of radio and X-ray light. But they should also result in the emission of gravitational waves, and LISA will be sensitive to those. For the first time, we’ll be able to see supermassive black holes in gravitational waves.”

There’s no doubt that LIGO has given us one of the most incredible breakthroughs of the 21st century: the direct detection of gravitational waves. But as wonderful as LIGO is, so far it’s only been able to detect the very final stages of mergers of stellar mass-scale black holes, and only every few months at that. The technique of laser interferometry is sound and powerful, but properties inherent to Earth itself fundamentally limit how good LIGO can potentially be. But these restrictions go away if we go to space! Not only can we eliminate seismic noise, cease accounting for the curvature of the Earth, and get a better vacuum for free, but we can achieve much longer baselines. By sending a series of spacecraft up into orbit behind the Earth, we can detect more massive, more distant, and slower-period sources than LIGO could ever hope to see.

LISA is the gravitational wave observatory of the future, and the European Space Agency just greenlit it for 2034! Come get the exciting news and find out what science it will be able to do today!___

While yesterday's solstice brought summer to planet Earth's northern hemisphere, a northern summer solstice arrived for ringed planet Saturn nearly a month ago on May 24. Following the Saturnian seasons, its large moon Titan was captured in this Cassini spacecraft image from June 9. The near-infrared view finds bright methane clouds drifting through Titan's northern summer skies as seen from a distance of about 507,000 kilometers. Below Titan's clouds, dark hydrocarbon lakes sprawl near the large moon's now illuminated north pole.

As also already "prophesied" last year by the esteemed and my good friend, Dr. +Rhys Taylor (See here https://plus.google.com/u/0/+RhysTaylorRhysy/posts/JeFx13ZJ1BB)

“[T]he whole motivation that Batygin and Brown’s theory relies on isn’t that “these objects exist,” but rather that “these objects exist and their clustering is very unlikely to happen just by chance.” But the likelihood of what you see relies heavily on where you’ve observed and with what sensitivity you’ve made those observations. If you find clustered objects because you spent more of your observing time looking in the locations where you’d see clustering, that doesn’t mean there’s anything unusual. In fact, it’s more likely, if that’s the case, that there isn’t anything unusual; it’s more likely that you’re the victim of a phenomenon called detection bias.”

Last year, scientists Konstantin Batygin and Mike Brown made a huge splash when they announced that the Solar System likely contained a super-Earth-sized object beyond the orbit of Neptune. They dubbed the world ‘Planet Nine,’ and claimed that it was responsible for the orbits of the longest-period Trans-Neptunian Objects ever discovered. The fact that the orbits were clustered in both ecliptic latitude and longitude cried out for an explanation, and Planet Nine fit. But an additional world isn’t the only plausible cause of the clustering of these distant objects; another possibility is that the hitherto discovered objects were biased in some way. If you’re only searching for objects in the locations that would show you these correlations, then you’re going to find the correlations. The solution? To do a survey capable of distinguishing between whether the effect is solely due to bias, or the existence of Planet Nine.

The first comprehensive, four-year results from OSSOS are now in, and with eight candidate TNOs with the right properties, they don’t see any signature for Planet Nine. Looks like the evidence has gone up in smoke!___As also already "prophesied" last year by the esteemed and my good friend, Dr. +Rhys Taylor (See here https://plus.google.com/u/0/+RhysTaylorRhysy/posts/JeFx13ZJ1BB)

Fascinating stuff..Resolving "Airglow Anomalies"

"Dating back to the first century, scientists, philosophers and reporters have noted the occasional occurrence of "bright nights," when an unexplained glow in the night sky lets observers see distant mountains, read a newspaper or check their watch.

A new study accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union, uses satellite data to present a possible explanation for these puzzling historical phenomena.

The authors suggest that when waves in the upper atmosphere converge over specific locations on Earth, it amplifies naturally occurring airglow, a faint light in the night sky that often appears green due to the activities of atoms of oxygen in the high atmosphere.

Fascinating stuff..Resolving "Airglow Anomalies"

"Dating back to the first century, scientists, philosophers and reporters have noted the occasional occurrence of "bright nights," when an unexplained glow in the night sky lets observers see distant mountains, read a newspaper or check their watch.

A new study accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union, uses satellite data to present a possible explanation for these puzzling historical phenomena.

The authors suggest that when waves in the upper atmosphere converge over specific locations on Earth, it amplifies naturally occurring airglow, a faint light in the night sky that often appears green due to the activities of atoms of oxygen in the high atmosphere. Normally, people don't notice airglow, but on bright nights it can become visible to the naked eye, producing the unexplained glow detailed in historical observations.

Few, if any, people observe bright nights anymore due to widespread light pollution, but the new findings show that they can be detected by scientists and may still be noticeable in remote areas. Bright airglow can be a concern for astronomers, who must contend with the extra light while making observations with telescopes.

"Bright nights do exist, and they're part of the variability of airglow that can be observed with satellite instruments," said Gordon Shepherd, an aeronomer at York University in Toronto, Canada, and lead author of the new study."

"Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have found new evidence suggesting that a jet of fast-moving material ejected from one young star may have triggered the formation of another, younger protostar.

"The orientation of the jet, the speed of its material, and the distance all are right for this scenario," said Mayra Osorio, of the Astrophysical Institute of Andalucia (IAA-CSIC) in Spain. Osorio is the lead author of a paper reporting the findings in the Astrophysical Journal."

Rare Helium Rich Star found. GALEX J184559.8−413827 is the first Ehe (Extreme helium star) star to be discovered after ~40 years

"(Phys.org)—Astronomers have identified another rare example of an extreme helium star. The star, designated GALEX J184559.8−413827 (or J1845−4138 for short), was initially classified as a faint helium-rich "hot subdwarf," but new spectroscopic observations reveal that this star is more hydrogen-deficient than previously thought. The finding is available in a paper published June 11 on arXiv.org.

Extreme helium stars (EHes) are supergiants much larger and hotter than the sun, but less massive. They are almost devoid of hydrogen, which is unusual, as hydrogen is the most abundant chemical element in the universe. EHes are characterized by relatively sharp and strong lines of neutral helium, which indicates low surface gravitiesand atm... more »

Extreme helium stars (EHes) are supergiants much larger and hotter than the sun, but less massive. They are almost devoid of hydrogen, which is unusual, as hydrogen is the most abundant chemical element in the universe. EHes are characterized by relatively sharp and strong lines of neutral helium, which indicates low surface gravities and atmospheres dominated by helium. Besides helium, these stars also have significant amounts of carbon, nitrogen and oxygen. EHe was first detected in 1942."

Abstract
A high-resolution spectrum of the helium-rich 'hot subdwarf' GALEX J184559.8-413827 (J1845-4138) obtained with SALT HRS demonstrates it to be the first extreme helium (EHe) star to be discovered in nearly 40 years. A quantitative analysis demonstrates it to have an atmosphere described by Teff = 26 170 +/- 750 K, log g /(cm s^2) = 4.22 +/ 0.10, and a surface chemistry characterised by CNO-processed helium, a 1% contamination of hydrogen (by number), and a metallicity 0.4 dex subsolar. Its distance and position are consistent with membership of the Galactic bulge. Its sharp absorption lines place strong constraints on both the rotation and microturbulent velocities. Spectroscopically, J1845-4138 closely resembles the pulsating EHe star V652 Her, generally considered to be the product of a double helium white dwarf merger evolving to become a helium-rich sdO star."

"Since the mid-1990s, when the first planet around another sun-like star was discovered, astronomers have been amassing what is now a large collection of exoplanets—nearly 3,500 have been confirmed so far. In a new Caltech-led study, researchers have classified these planets in much the same way that biologists identify new animal species and have learned that the majority of exoplanets found to date fall into two distinct size groups: rocky Earth-like planets and larger mini-Neptunes. The team used data from NASA's Kepler mission and the W. M. Keck Observatory.

1,000 Days in Orbit: MAVEN’s Top 10 Discoveries at Mars

On Saturday, June 17, 2017, the #MAVEN mission surpassed 1,000 Earth days in orbit around the Red Planet. Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of #Mars.

MAVEN is bringing insight to how the sun stripped away most of the #Martian atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.

As part of its mission to survey as much of the entire night sky as possible in visible light, the ESO’s VLT Survey Telescope (VST) has just released a 3.3 gigapixel composite of a region of the Milky Way containing three spectacular nebulae: the Omega Nebula, the Eagle Nebula, and Sharpless 2-54. While the Omega Nebula is similar to the Orion Nebula and the Eagle Nebula is larger and still active, Sharpless 2-54 is an ionized region caught in-between waves of star formation, presently inactive. The brilliant young clusters visible inside are all that will be left of all these nebulae once the gas burns away.
