Milky Way Galaxy May Have Formed Inside-Out, Study

Jan 21, 2014 by Sci-News.com

Our Milky Way Galaxy formed by expanding out from the center, suggests analysis of first data from the Gaia-ESO survey – the ground-based extension to the Gaia space mission, launched by the European Space Agency at the end of 2013.

The astronomers involved with the Gaia-ESO project took detailed observations of stars with a wide range of ages and locations in the Galactic disc to accurately determine their ‘metallicity’: the amount of chemical elements in a star other than hydrogen and helium, the two elements most stars are made from.

Immediately after the Big Bang, the Universe consisted almost entirely of hydrogen and helium, with levels of “contaminant metals” growing over time. Consequently, older stars have fewer elements in their make-up – so have lower metallicity.

“The different chemical elements of which stars are made are created at different rates – some in massive stars which live fast and die young, and others in sun-like stars with more sedate multi-billion-year lifetimes,” said Prof Gerry Gilmore from the University of Cambridge, who is a co-author of the paper submitted to the journal Astronomy and Astrophysics (arXiv.org version).

Massive stars, which have short lives and die as ‘core-collapse supernovae’, produce huge amounts of magnesium during their explosive death throes. This catastrophic event can form a neutron star or a black hole, and even trigger the formation of new stars.

Scientists discovered three new planets orbiting stars in a cluster about 2,500 light years from Earth. Remarkably, among them they found an exoplanet orbiting a star which is almost identical to our own Sun in all respects.

The fascinating find was made by astronomers from the Max Planck Institute for Extraterrestrial Physics in Germany. They have been monitoring 88 promising-looking stars in a formation called Messier 67 for the past six years. Messier 67 is a cluster of about 500 stars in the constellation of Cancer.

The discovery is so exciting because it is the first time astronomers have found an exoplanet orbiting a star which is almost identical to our sun, in a cluster of stars. The star, similar to the sun in mass, temperature and chemical composition, was named YBP1194.

The second planet that was discovered is also orbiting a star similar to the Sun. The third one is circling a more massive and evolved red giant star.

All Sky Fireball Network

by Dr. Tony Phillips.

 

Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by NASA’s Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth’s atmosphere and many other characteristics. Daily results are presented here on Spaceweather.com.

On Jan. 11, 2014, the network reported 14 fireballs.
(14 sporadics)

In this diagram of the inner solar system, all of the fireball orbits intersect at a single point–Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies]

 

Near Earth Asteroids

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.

On January 12, 2014 there were 1450 potentially hazardous asteroids.

SPACE WEATHER BALLOON UPDATE:

by Dr. Tony Phillips.

The payload of a space weather balloon launched Jan. 8th by the students of Earth to Sky Calculus has been recovered from its landing site in Death Valley National Park. The purpose of the flight was to study a solar radiation storm in progress at the time of the launch. Analyzing the data may take a few days. Meanwhile, here is the view from the stratosphere:

These pictures were taken by a pair of Hero3+ cameras looking out of the payload capsule. The upper frame shows the Sierra Nevada mountain range, unusually brown for this time of year as California endures a historic drought. The lower frame captures the balloon popping at an altitude of approximately 100,000 feet. Click on each frame for a closer look. The landscape shot was made using the Hero3+’s new “superview mode”–a favorite of snowboarders and now, for the first time, balloonists!

In addition to cameras, the payload contained an x-ray/gamma-ray dosimeter, a GPS altimeter, and a cryogenic thermometer. Together these instruments can form a complete thermal and radiation profile of the atmosphere throughout the flight. The students plan to pay special attention to data collected at aviation altitudes to learn how much radiation air travelers absorb during periods of high solar activity.

Jan. 16 May Be Last Best Chance to Search for Comet ISON’s Remains

Comet ISON revolves around the sun in steeply inclined orbit. Earth will pass through the plane of that orbit on Jan. 16. As we look "up" toward the comet our edgewise perspective could cause a temporary brightening of ISON's dust remnant. Credit: solarsystemscope.com with annotations by the writer.

Is there any hope of detecting what’s left of Comet ISON after the sun proved too much for its delicate constitution? German amateur astronomer Uwe Pilz suggest there remains a possibility that a photographic search might turn up a vestige of the comet when Earth crosses its orbital plane on January 16, 2014.

Comet ISON is located high in the northern sky near the familiar "W" or "M" or Cassiopeia during the time of orbital crossing. Stellarium

On and around that date, we’ll be staring straight across the sheet of debris left in the comet’s path. Whatever bits of dust and grit it left behind will be “visually compressed” and perhaps detectable in time exposure photos using wide-field telescopes. To understand why ISON would appear brighter, consider the bright band of the Milky Way. It stands apart from the helter-skelter scatter of stars for the same reason; when we look in its direction, we peer into the galaxy’s flattened disk where the stars are most concentrated. They stack up to create a brighter band slicing across the sky. Similarly, dust shed by Comet ISON will be “stacked up” from Earth’s perspective on the 16th.

MINOR RADIATION STORM IN PROGRESS:

Energetic protons are swarming around Earth on Dec. 28th following a magnetic eruption near the western limb of the sun: movie. The ongoing radiation storm ranks S1 on NOAA storm scales, which means it is a relatively minor storm with little effect on spacecraft and high-altitude aviation

CRACKLING SUNSPOT:

by Dr. Tony Phillips.

AR1936 is waking up. The sunspot has a ‘beta-gamma-delta’ magnetic field that harbors energy for strong eruptions, yet it has been quiet for days. Now AR1936 is beginning to crackle with flares. NASA’s Solar Dynamics Observatory recorded the extreme ultraviolet flash from an almost-M-class flare at 1800 UT on Dec. 28th:

Because the sunspot is facing Earth, any flares emanating from it are going to be geoeffective. So far, the extreme ultraviolet “crackles” have produced only minor waves of ionization in our planet’s upper atmosphere. Earth-effects will increase, however, if the activity continues to intensify.

NORTH LIBERTY, Iowa – People across the Midwest reported seeing a bright fireball streak across the sky Thursday evening … and it was caught on camera in North Liberty.

The fireball, a possible meteor, was spotted at about 5:40 p.m. Thursday. Reports indicated that it was seen across many Midwestern states, including Iowa, Illinois, Minnesota, Missouri, Wisconsin, Nebraska and South Dakota.
