Space Events Not To Be Missed In 2017

(Yahoo News UK) – With a solar eclipse due on 26 February, there are plenty of celestial treats to keep stargazers happy in 2017.

Last year was packed with astronomical action including supermoons, Tim Peake’s history-making spacewalk and the arrival of NASA’s Juno probe at Jupiter and this year is set to be big just as big for space botherers. From meteor showers to solar eclipses, here are the space events you don’t want to miss in 2017…

  1. Annular solar eclipse – 26 February 2017
    At the end of February, the moon will pass in front of the sun, creating a bizarre halo effect. Unfortunately, this year’s eclipse will only be visible over South and West Africa and some of South America. 

  2. Jupiter at opposition – 7 April 2017
    The largest planet in our solar system will reach ‘opposition’ in April, meaning that it will slide into view as Earth moves into position between the sun and Jupiter. The massive planet’s face will be illuminated by the sun and will be visible through binoculars or a telescope. 

  3. Saturn at opposition – 15 June 2017
    In summer, Saturn will move into its closest position to Earth, giving us the best view possible. A telescope will be needed to see the huge planet’s famous rings while Saturn is fully lit up by the sun. 

  4. Perseid meteor shower – 12/13 August 2017
    One of the brighter meteor showers of the year, the Perseids happens annually between 17 July and 24 August, this year peaking 12-13 August. The best time to view the shooting stars is between midnight and dawn. 

  5. ‘Great American’ total solar eclipse – 21 August 2017
    For around two minutes, a 70-mile stretch between Oregon and South Carolina will be plunged into total darkness in a rare total eclipse as the sun will totally disappear behind the full moon. Stargazers elsewhere in the US will get a partial view of the stunning eclipse. 

  6. Cassini probe will crash into Saturn – 15 September 2017
    Launched in 1997, NASA’s probe finally made it to Saturn in 2004 and has been beaming back vital data to Earth ever since. The probe will be destroyed when it plunges through Jupiter’s atmosphere but not before sending back never-seen-before images. 

  7. Leonid meteor shower – 17/18 November 2017
    The Leonids meteors will be visible in the night sky throughout November, peaking between 17 and 18 November. The glowing pieces of comet debris will be visible to the naked eye. 

  8. Supermoon – 3 December 2017
    While 2016 saw stargazers treated to several supermoons, 2017 will see just one. December’s full moon, also known as the Full Cold Moon, will appear slightly bigger and brighter than normal. The best time to watch will be around sunset when the distinctive orange moon will appear.

  9. Geminid meteor shower – 13/14 December 2017
    Unlike most meteor showers, the Geminids are associated with an asteroid, rather than a comet. The glowing fireballs should be visible to the naked eye between December 7 and 16, but the best time to catch a glimpse is between 13 and 14 December. 

A Real Life Ice Age On The Way?

A real life ice age?

Below is an article from the Yahoo News:

The Sun Has Just ‘Gone Blank’ – Could There Be An Ice Age On The Way? – By Rob Waugh

Don’t be alarmed, but our sun has just ‘gone blank’ – with a total lack of sunspots leaving the surface like a snooker ball.

It’s part of the sun’s cycles – a sign that the ‘solar minimum’ is approaching – and some experts have suggested a new ‘mini ice age’ might be on the way.

Meteorology expert Paul Dorian of Vencore Weather says, ‘For the second time this month, the sun has gone completely blank.

‘The blank sun is a sign that the next solar minimum is approaching and there will be an increasing number of spotless days over the next few years.

‘At first, the blankness will stretch for just a few days at a time, then it’ll continue for weeks at a time, and finally it should last for months at a time when the sunspot cycle reaches its nadir.  The next solar minimum phase is expected to take place around 2019 or 2020.’

Some experts predict that we could soon see a ‘Maunder minimum’ phase – a mini ice age similar to one which began in 1645.

During the ‘Maunder Minimum’, temperatures plunged so much that the Thames froze over.

Prof Valentina Zharkova of Northumbria University  predicts that there will be a sharp decline in solar activity between 2020 and 2050.

Zharkova said, last year, ‘I am absolutely confident in our research. It has good mathematical background and reliable data, which has been handled correctly. In fact, our results can be repeated by any researchers with the similar data available in many solar observatories, so they can derive their own evidence of upcoming Maunder Minimum in solar magnetic field and activity.’

Photos And Video: Mexican Fishermen Found Conjoined Gray Whale Calves

MEXICO CITY (AP) — The Mexican government says fishermen found two rare conjoined gray whale calves that died shortly after being born.

Biologist Benito Bermudez says the whales were found alive in the Ojo de Liebre lagoon in the Baja California Peninsula but lived only a few hours.

Bermudez said Wednesday they were linked at the waist, with two full heads and tail fins.

Bermudez is a marine biologist with the National Natural Protected Areas Commission, or CONANP. He said scientists are collecting skin, muscle and baleen samples to study the creatures.

Every year more than 20,000 gray whales swim to Mexico from Alaska to mate and give birth.

Fishermen have found two conjoined gray whale calves in a northwestern Mexican lagoon, a discovery that a government marine biologist described as "exceptionally rare."

Fishing For Arapaima, Brazil’s Living Fossil – Photos

Fishing for a living fossil?

Reuters reported that a type of fish named arapaima or pirarucu is considered by biologists to be a living fossil.

Arapaima is the largest freshwater fish species in South America and one of the largest in the world,

Catching the arapaima, a fish that is sought after for its meat, is only allowed once a year by Brazil’s environmental protection agency.

The minimum size allowed for a fisherman to keep an arapaima is 1.5 meters.

Photos: 2013 Supermoon, When Moon At Closest Point To Earth

JER03. Har El (Israel), 23/06/2013.- A full moon in the 'Perigee' phase rises over the Jerusalem neighborhood of Har El, 23 June 2013. The moon on 23 June evening will be at its closest distance to Earth, a constellation also known as 'supermoon,' in which the earth's trabant appears between 12 to 14 per cent larger and according to scientific sources also about 30 percent brighter than the normal full moon.

Supermoon happens when the moon on its elliptical orbit is at its closest point to Earth.

So, we will see it bigger than usual.

The moon can appears to be up to 14%  larger and 30% brighter than when the moon is at its farthest point, or apogee.

Here are some cool photos of the supermoon around the world ….

At the end of May 2013,  Jupiter, Venus and Mercury form a celestial triangle in the night sky.

The three planets shine together in a triangle formation low in the western sky in a planetary meet-up known as a conjunction.

We can even see them with naked eyes if the sky is clear and the place is not too bright.

This cosmic show is so special spectacular because it includes the three brightest planets visible in the May night sky.

Venus is the brightest of the trio, with Jupiter a close second and Mercury coming in third.

Flickr photographers snapped awesome photos of this very rare and special event.

Wild Watersprouts Pictures

Here are photos of waterspouts around the world during the 21st century.

A waterspout is a tornado or twister over water instead of over the land.

Waterspout can cause disaster; if a waterspout hits a ship, it could crush them into pieces.

If a waterspout moves onshore, the National Weather Service issues a tornado warning, as some of them can cause significant damage and injuries to people.
