Astronomers Discover New Earths In Our Celestial Neighborhood

Kevin Enochs
February 22, 2017

An international team of astronomers, using an array of ground
and space telescopes, has discovered an astonishing seven
Earth-sized planets in a system just 40 light years away.

Water, water everywhere

The seven planets, according to a press release, "all have masses
less than or similar to the Earth."

According to scientists, the temperatures on the planets "are low
enough to make possible liquid water on the surfaces..." as the
planets are in that perfect habitable or "goldilocks zone,"

Michaël Gillon, of the STAR Institute at the University of Liège
in Belgium, is the study's lead author. Gillon says he is
delighted by the findings. "This is an amazing planetary system
-- not only because we have found so many planets, but because
they are all surprisingly similar in size to the Earth!"

The new findings are outlined in today's journal Nature.

Dwarf stars - who knew?

The planets were discovered orbiting around a small, ultracool
(as in temperature) star called TRAPPIST-1.

It is similar to another dwarf star, Proxima Centauri, that's
just 4.2 light years away from Earth. It also made news last year
when scientists discovered an Earth-like planet, dubbed Proxima
b, in its orbit that is also in the goldilocks zone.

These Earth-like planets are no surprise to Alan Boss, an
astrophysicist who spoke to VOA about Proxima b a few months ago.
Back then he said there may be as many as "1.2 habitable Earths
per star."

Finding the planets was an international effort. Astronomers had
already discovered three Earth-sized planets orbiting the star
last year. Those were discovered by monitoring so-called
'transits,' when planets cross in front of the star, dimming
their light.

So researchers decided to take a closer look and monitored the
star "for months with different telescopes in Chile, Morocco,
Hawaii, La Palma and South Africa, and in September 2016, NASA's
Spitzer Space Telescope monitored TRAPPIST-1 for 20 days."

Their work discovered four more planets, all of which "could
potentially have liquid water on their surfaces."

The researchers say all of the planets are about the same sizes
as Earth or Venus, but any resemblance to our solar system ends
there.

For one, everything is smaller on TRAPPIST-1, beginning with the
star itself, which is only about 8 percent the size of our sun,
making it just a bit larger than our largest planet, Jupiter.
That puts all seven of these planets "in far closer orbits than
we see in the solar system."

And more information is on the way. The James Webb Space
Telescope will be launched in 2018 and will be able to take an
even closer look at the planets around TRAPPIST-1.

Brice-Olivier Demory, one of the authors and a professor at the
University of Bern's Center for Space and Habitability, says
adding the Webb Telescope into the mix will allow us to move
beyond looking for planets, and instead start looking for life.
"The James Webb Space Telescope," he says, "Hubble's successor,
will have the possibility to detect the signature of ozone if
this molecule is present in the atmosphere of one of these
planets...This could be an indicator for biological activity on
the planet."

He says that making definitive statements concerning life beyond
Earth will never be simple, but like Boss told VOA last year," I
expect to still be alive when it happens."

HAARP Signals Widely Copied, Experiments to Continue

02/20/2017

Many listeners were able to copy signals from Alaska's High
Frequency Active Auroral Research Program (HAARP) early on
February 20 (UTC). The facility has begun its first scientific
research campaign since being taken over by the University of
Alaska Fairbanks (UAF) Geophysical Institute 18 months ago. UAF
Space Physics Group Assistant Research Professor Chris Fallen,
KL3WX, said the Twitter and e-mail feedback from his first
evening's run has been "fantastic." Fallen will fire up the
powerful HAARP transmitters again on February 21 starting at 0300
UTC (the evening of February 20 in US time zones) with a few
tweaks.

"I may adjust the frequency to 2.83 MHz and 3.33 MHz, but
generally it will be 2.8-ish and 3.3-ish either way," he told
ARRL.

Fallen is starting and stopping each experiment block with an
audio broadcast, transmitting AM carriers on or about 2.8 and 3.3
MHz, with the resulting skywave signal - the "Luxembourg Effect"
- being a mix of both frequencies. He has transmitted a simple
piece of music, composed locally, specifically to help
demonstrate the Luxembourg effect. Fallen said he got reports on
the first evening from Georgia, Michigan, British Columbia,
Southern California, and Finland - among other locations.

"The CW artificial aurora experiment that follows (weather
dependent) is 90 seconds on, 30 seconds off, with the following
sequence: 2.80, 2.80, 2.82, 2.84 MHz," Fallen said. "The
ionosphere has been looking ratty all day, so I do not have much
hope for the artificial aurora experiments."

He said his Twitter feed (@ctfallen) has included "a lot of great
waterfalls, videos, and audio by hams and SWLers. It's quite an
event, of sorts."

Fallen is working under a National Science Foundation grant. He's
posting additional information on his "Gakona HAARPoon 2017"
blog. He points out that exact times, transmit frequencies, and
experiment modes "are subject to change in response to a variety
of factors." Selected updates will be posted via Twitter.

Fallen encourages radio amateurs and SWLs to record the events
they hear and post reports to social media or e-mail him.

Arctic 'Doomsday' Seed Vault Receives 50,000 New Deposits

Associated Press via voanews.com
February 23, 2017

HELSINKI - Nearly 10 years after a "doomsday" seed vault opened
on an Arctic island, some 50,000 new samples from seed
collections around the world have been deposited in the world's
largest repository built to safeguard against wars or natural
disasters wiping out global food crops.

The Svalbard Global Seed Vault, the world's largest agricultural
gene bank located on the Svalbard archipelago between mainland
Norway and the North Pole, was built as a master backup to the
world's other seed banks.

A research center that focuses on improving agriculture in dry
zones - the first to retrieve its seed collection from the vault
in 2015 - on Wednesday returned some 15,000 specimens after
multiplying and reconstituting them. The collections range from
India to the Middle East, northern Africa and the Americas.
