NASA says Voyager 2 may be nearing interstellar space

perth_map

So until Voyager 2 passes through the heliopause, there's no way to be sure precisely where it is with regard to the heliopause. In 2007 the probe reached and started to travel through the outermost parts of the heliosphere-the "bubble of protection" that comes from the magnetic fields of the Sun and the planets in the Solar System .

MI meteorite used as doorstop for 30 years 'worth $100,000'

perth_map

But this chunk was from a much older asteroid: When the man from Grand Rapids, Michigan , bought his farm in the Edmore, Michigan, area in 1988, the previous owner told him that the doorstop was a meteorite from the 1930s. What's 88.5 percent iron, 11.5 percent nickel and worth $100,000? "I wonder what mine is worth", Mazurek said in the release. "It was in the barn, one of the outside sheds, just laying on a shelf", David Mazurek said. Read More »

SpaceX to launch and land Falcon 9 rocket from Southern California

Shortly afterward SpaceX showed a shot of Falcon 9, successfully landed on landing zone 4. Residents in Santa Barbara, Ventura and San Luis Obispo counties also may hear sonic booms. The sound of the boom will depend on weather conditions and other factors. "What you're looking at is the first launch and landing of the @SpaceX Falcon 9 rocket on the West Coast". Read More »

Massive LNG project in northern BC reportedly given the go-ahead

He says this shows Canada's commitment to combatting the problem of climate change by driving down emissions world wide. Wetselaar said global demand for LNG has grown 9 per cent in the previous year alone and the LNG the project will produce is half as emission-intensive as coal, a power source which Asian countries are trying to replace with LNG.

Gaia Satellite Sees Stars Flying Between Galaxies

perth_map

Of the extragalactic stars the paper proposes, it's the delightfully named Gaia DR2 1396963577886583296, with a velocity of over 700 kilometres per second, that has the highest probability of visiting from another galaxy. On the other hand, scientists do not exclude that these stars were once able to be part of a binary system and be disposed of after a supernova explosion. Read More »

Astronomers may have discovered the first moon outside Earth's Solar System

perth_map

NASA's planet-hunting Kepler spacecraft , with an assist from the more powerful Hubble Space Telescope , has found what appears to be a huge moon orbiting a gas giant planet 8,000 light years away. "The first eczema is an extraordinary statement that requires extraordinary proof", said the astronomer, Columbia University David KPMG. As per the study researchers, this is the best candidate so far and they have already nicknamed it as candidate satellite a "Nept-moon", because of its ... Read More »

What Cassini's Final Descent Into Saturn Taught Us About Its Rings

perth_map

The team identified the composition of dust particles that fall from Saturn's rings toward the planet. Linda Spilker is the NASA Cassini spacecraft project scientist at the Jet Propulsion Laboratory (JPL). Another finding is that Saturn's magnetic field has poles that perfectly match up with its rotational axis and that is really unusual because as on Earth, Jupiter and even Neptune, scientists believed that by requirement, a planet's magnetic field normally matches up to its spin axis.

Jewish Nobel Prize victor who coined term 'God particle' dies aged 96

perth_map

Leon Lederman himself said that his publisher preferred this title instead of the one he wanted the writer ("the cursed particle"), because he escaped the discovery for many years after the theoretical conception of his existence by British natural Peter Higgs, but also because, as he said, "there is a connection of some sort with another book, much older ...", meaning the Bible.

Florence death toll in North Carolina rises by 2, to 39

perth_map

Two people died in North Carolina while repairing damage from the hurricane in late September, bringing the number of storm-related deaths in that state to 39, Governor Roy Cooper said on Tuesday. Cooper urged North Carolina residents to apply for assistance from the federal government as they look to rebuild. Scott Harrelson, the health director of Craven County, which is among those affected, was quoted as thanking Cooper for helping provide "a critical public health service" in the wake ... Read More »

Chance of tropical depression or tropical storm developing in Gulf has increased

perth_map

But as this area drifts slowly north through the weekend into early next week shear will begin to lessen, and it's possible a tropical depression or weak tropical storm will form. "Odds favor that a storm emerging from the northwestern Caribbean will track toward the northeastern Gulf of Mexico rather than the Texas coastline this time of year", he said. Read More »

First ever ‘exomoon’ discovered orbiting planet outside our solar system

perth_map

With a lot of help from the Hubble Space Telescope , astronomers now feel confident enough to publish their evidence for the first moon detected in orbit around a planet beyond our solar system. There are two ways to potentially identify an exomoon . Is it really a moon? There's no indication of another planet in the system that could be tugging on Kepler-1625b, and the secondary dimming is consistent with a moon trailing the gas giant during its transit.

Hurricane Leslie is roughly 510 miles ESE of Bermuda with winds of 70kts. Leslie grew in intensity Wednesday morning with wind speeds of 120 km per hour and occasional faster gusts, the report said. Tropical Storm Leslie completed the transition to a fully-formed tropical system on Saturday. The tropics have been generally quiet after a whirlwind early September. Read More »

Jewish researcher, 96, shares Nobel Prize in physics

perth_map

But, as the list of winners of the different Nobels for Physics and Chemistry show, it might be better for the Nobel Prize Committee to actually consider giving prizes for the sciences in general, instead of segregating them into Physics and Chemistry prizes and not having a biology prize.

Farmer's "Doorstop" Valued At $100K After Incredible Discovery

This January, southern MI experienced a meteor flash that showered fragments of space rock all over Livingston County. The Smithsonian Institution in Washington, D.C., corroborated Sirbescu's analysis that the 22-pound "rock" is, indeed, a meteorite , and is apparently the sixth-largest of its type to be discovered in MI.

The new owner came into possession of the meteorite after the farm was sold in 1988. As the farmer was showing him around the property, they went out to a shed. The Smithsonian is considering purchasing the meteorite for display. If it can not purchase it, the slice will stay in the collection. It has been named the "Edmore" meteorite after the town in which the farm is located. Read More »

Astronomers reach breakthrough in mysterious 'Planet X' theory

perth_map

Science Magazine says that the discovery of the tiny dwarf planet was "a lucky one", as its elliptical orbit takes some 40,000 years to travel around the sun. But the planet may be most memorable for another discovery it portends. These orbits keep them from ever approaching the proposed planet too closely, similar to how Pluto never gets too close to Neptune even though their orbits cross. Read More »

Astronomers spot distant object that supports Planet Nine theory

The new extremely distant object far beyond Pluto has an orbit that supports the presence of a larger Planet X . The object was discovered as part of the team's ongoing hunt for unknown dwarf planets and Planet X. With Halloween less than a month away, the world of astronomy has certainly found itself dabbling in spooky topics, most notably the skull-shaped asteroid due to whizz past Earth not long after the holiday.

Massachusetts-sized object beyond Pluto hints at hidden Planet X

perth_map

But because of the theorised 10-20,000-year orbit cycle such a planet would have, pinpointing it has proven fairly bloody tricky, as you'd imagine. Those hoping for theoretical Earth-sized planets proposed by astrologers or science fiction writers - which are "hiding behind the sun" and linked with Doomsday scenarios - may have to keep searching.
