Solar activity is at very low levels and the visible disk remains spotless for the 17th day in a row, making a total of 33 days in 2020 or 66 percent — we are still in a Solar Minimum, which is expected to end sometime this year.

As a result of weakened Sun’s magnetic field in this very deep Solar Minimum, deep-space radiation is easily entering our solar system and affecting all planets within it, Earth included…..

This 3-D visualization flies across a small portion of the Veil Nebula as photographed by the Hubble Space Telescope.

This region is a small part of a huge expanding remnant from a star that exploded many thousands of years ago.

Hubble resolves tangled rope-like filaments of glowing gases. The 3-D model has been created for illustrative purposes and shows that that the giant bubble of gas has a thin, rippled surface.

It also highlights that the emission from different chemical elements arises from different layers of gas within the nebula. In the imagery, emission from hydrogen, sulfur, and oxygen are shown in red, green, and blue, respectively. Credit: NASA, ESA, and F. Summers, G. Bacon, Z. Levay, and L.

THE PHOTON-BELT ENCOUNTER
(January, 1998)

By Noel Huntley, Ph.D.

By means of satellite instrumentation, astronomers in 1961 discovered what appeared to be an unusual nebula. We normally understand the nebula phenomenon as a vast cloud-like mass of gas or dust. This one, however, appeared to have anomalous properties and was named the Golden Nebula.

The public’s attention was not drawn to this unusual revelation until much later, presumably when it was realised that this nebula’s location was coincident with the projected orbit of our solar system. Around the early 1980s a radio announcement in the U.S. was made (heard by the author) that our solar system was, in fact, going to collide with an ‘electromagnetic cloud’ in the not too distant future.

This incredibly important statement of astronomical and historical significance was expressed in the usual casual and indifferent manner as though of little consequence…..

Jellyfish Sprites Over Europe, 80 km high above the clouds

On June 20th, a thunderstorm in Austria unleashed a spectacular display of lightning. Observers on the ground witnessed blinding flashes of crackling light. The most amazing aspect of the outburst, however, was to be found high above the clouds. 80 km high, to be exact, in the realm of the sprites

Martin Popek photographed the display from his private observatory in Nýdek, Czechia, more than 500 km away from the storm. Such distances are ideal for seeing above the tops of towering thunderclouds: diagram.

“Jellyfish sprite events like these are produced by very impulsive cloud-to-ground lightning flashes draining positive charge from the stratiform rain region in large thunderstorms,” explains lightning scientist Oscar van der Velde of the Technical University of Catalonia, Spain. Somehow, in a process that researchers only partially understand, the resulting electric fields draw jellyfish forms out of the cloudtops.

The tops of the sprites were surrounded by a saucer-like halo of red light, notes van der Velde. “The halo is evidence of intense electric fields at 80-90 km shaking up the electrons (colliding with nitrogen to produce light) for such a short time that sprite streamers cannot form. At lower altitudes the field exists longer, allowing the jellyfish sprite streamers to grow from electron avalanches.”

Although sprites have been seen for at least a century, most scientists did not believe they existed until after 1989 when sprites were photographed by cameras onboard the space shuttle.

Amazing Earth-sized planet dubbed the ‘iceball’ discovered by NASA

Posted in 2017, astronomy, Galaxy, Uncategorized with tags , , , , on April 27, 2017 by theboldcorsicanflame
59021059c461883a158b45c6.jpgNASA has discovered a planet the same size as Earth, and the same distance from its star as our planet is from the sun.

Due to its small size, the host star does not produce enough heat to support life on the planet. This has prompted scientists to label the world – nominally called OGLE-2016-BLG-1195Lb – the ‘iceball’ planet.

An international team of researchers found the planet using a technique known as ‘microlensing,’ which uses background stars as flashlights that mark out planets as dark dots when they cross the field of light.

“This iceball planet is the lowest-mass planet ever found through microlensing,” said Yossi Shvartzvald, a NASA postdoctoral fellow based at the space agency’s Jet Propulsion Laboratory in Pasadena, California.

The study, published in Astrophysical Journal Letters, aims to increase our understanding of the different types of planetary systems, in particular the distribution and frequency of planets outside the central bulge of the Milky Way.

Some 13,000 light years away, the ‘iceball’ orbits an object so small that researchers believe it could be a brown dwarf, a star-like object not capable of generating energy through nuclear fusion.

Another theory suggests it’s an ultra-cool dwarf star like TRAPPIST-1, the recently discovered star found to be hosting seven Earth-like objects.

High above Earth in the realm of meteors and noctilucent clouds, a strange and beautiful form of lightning dances at the edge of space

Researchers call the bolts “sprites”; they are red, fleeting, and tend to come in bunches. Note to sky watchers: Sprite season is underway. Martin Popek photographed these specimens over Nydek, Czech republic, on May 13th

One night later, May 14th, near Santa Fe, New Mexico, “I captured my first sprites of the season,” reports photographer Jan Curtis. “The thunderstorm that produced them was about 200 miles to my south-southwest.”

Because sprites are associated with thunderstorms, they tend to occur in late spring and summer. Thunderstorm season is sprite season.

“Sprites are a true space weather phenomenon,” explains lightning scientist Oscar van der Velde of the Technical University of Catalonia, Spain. “They develop in mid-air around 80 km altitude, growing in both directions, first down, then up. This happens when a fierce lightning bolt draws lots of charge from a cloud near Earth’s surface. Electric fields [shoot] to the top of Earth’s atmosphere–and the result is a sprite. The entire process takes about 20 milliseconds.”

Although sprites have been seen for at least a century, most scientists did not believe they existed until after 1989 when sprites were photographed by cameras onboard the space shuttle. Now “sprite chasers” routinely photograph sprites from their own homes. “I used up a Watec 910HX security camera with UFOCapture software to catch my sprites,” says Popek. Give it a try!

Seth Shostak, a Senior astronomer at Seti Institute Claims: “We could find alien life but politicians don’t want to”

Data suggests our galaxy has 40 billion planets with potential for life But finding these depends on sophisticated and expensive experiments
‘Sadly much of this reconnaissance hardware is still on the drawing boards, not in space,’ said Dr Shostak

They suggest proof may come within a generation. These scientists support their sunny point of view with a few astronomical facts that were unknown a generation ago.

In particular, and thanks largely to the success of Nasa’s Kepler space telescope, we can now safely claim that the universe is stuffed with temperate worlds.

In the past two decades, thousands of planets have been discovered around other stars. New ones are turning up at the rate of at least one a day.

WE WILL FIND ALIEN LIFE IN 20 YEARS, CLAIMS NASA

40 billion worlds in our galaxy could host alien life, according to a recent study. And Nasa claims that we will be able to find that life within the next 20 years, with a high chance it will be outside our solar system.

During a public talk last month in Washington, the space agency outlined a roadmap to search for life in the universe using a number of current and future telescopes. Do we believe there is life beyond Earth?’ said former astronaut and Nasa Administrator Charles Bolden.

‘I would venture to say that most of my colleagues here today say it is improbable that in the limitless vastness of the universe we humans stand alone.’

Series of experiments could shed new light on the ‘multiverse’

WHAT IS THE MULTIVERSE THEORY?

The term ‘multiverse’ was invented in December 1960, by Andy Nimmo, then vice chairman of the British Interplanetary Society.

It is based on the theory of eternal inflation, which suggests that shortly after the Big Bang that formed the universe, space-time expanded at different rates in different places.

According to eternal inflation theory, this gave rise to bubble universes that may function with their own separate laws of physics.

The idea of other universes out there may seem strange, but scientists say it can help solve some problems of fundamental physics.

For instance, the long-standing mystery of why nature appears to be fine-tuned for the emergence of life can be explained by the picture of a multiverse.

Some scientists argue that intelligent observers exist only in those rare areas in which the conditions happen to be just right for life to evolve.

The rest of the multiverse remains barren, but no one is there to notice it.

 

Scientists Discover Two Most Distant Stars Ever Detected in Milky Way Galaxy

A team of astronomers using the Red Channel spectrograph at the MMT Observatory on Mt. Hopkins in Arizona has discovered the most distant Milky Way stars known to date – ULAS J001535.72+015549.6 and ULAS J074417.48+253233.0. These cool red giants are extremely far away, at distances of 775,000 and 900,000 light years, respectively.

The distant outskirts of our Milky Way Galaxy harbor valuable clues for understanding the formation and evolution of the Galaxy.

Yet, due to overwhelming distances and an extremely sparse population of stars, many objects have not been identified beyond 400,000 light years, with only seven stars known to date beyond this limit.

The team led by Prof John Bochanski of Haverford College has now discovered two stars in the Milky Way’s outer halo that are the most distant ever discovered in our Galaxy.

May 23rd 2014: ANTICIPATION BUILDS FOR TONIGHT’S METEOR SHOWER

Earth won’t be the only body passing through the debris zone. The Moon will be, too. Meteoroids hitting the lunar surface could produce explosions visible through backyard telescopes on Earth. The inset in this picture of an actual lunar meteor shows the region of the crescent Moon on May 24th that could be pelted by May Camelopardalids

This weekend, Earth will pass through a stream of debris from Comet 209P/LINEAR. If forecasters are correct, the encounter could produce an outburst of bright meteors numbering more than 200 per hour.  Most models agree that peak rates should occur between the hours of 0600 UT and 0800 UT (2 a.m. and 4 a.m. EDT) on Saturday morning, May 24th, a time frame that favors observers in North America.  It is worth noting, however, that Earth has never encountered this stream of debris before, so forecasters cannot be certain of their predictions.  The display could be a complete dud, a fantastic “meteor storm,” or anything in between. Whatever happens, NASA plans to chat about it.

“Peaking at a magnitude of -2 (Mars brightness), our now-extinct visitor was about 3.3 cm in diameter – a little smaller than a ping pong ball,” continues Cooke. “We believe it was a May Camelopardalid because it had an orbit that greatly resembles that of parent Comet 209P/LINEAR.” The diagram, below, shows the match:

“So why is this good?” asks Cooke. “Looking back to 2012, our computer models show very little comet debris near Earth. We predicted nothing, yet got one meteor. Does this mean that a legion of his siblings will show up this year, when the models suggest the potential of a full-fledged meteor outburst? I’m getting excited about Friday night/Saturday morning.”

A second radar map looks at meteoroid speed. The red regions indicate a speed of 7.5 miles/s (12km/s), the green from 26 miles/s (42km/s) and the blue from 41 miles/s (66km/s)

Maps produced using the space agency’s Asgard program which tracks an estimated 4,000-5,000 meteoroids a day

WHICH ROCK IS WHICH?

An asteroid is a large chunk of rock left over from collisions or the early solar system.

Most are located between Mars and Jupiter in the Main Belt.

A comet is a rock covered in ice, methane and other compounds. Their orbits take them much further out of the solar system.

A meteor is what we call a flash of light in the atmosphere when debris burns up.

This debris itself is known as a meteoroid. Most are so small they are vapourised in the atmosphere.

If any of this meteoroid makes it to Earth, it is called a meteorite

Meteors, meteoroids and meteorites normally originate from asteroids and comets.
