A stunning close encounter of the two brightest star-like objects in the sky is expected this week.

Venus, the brightest object in the sky and Jupiter, the largest planet -will huddle close together in the sunset skies this week.

This will be the planets’ nearest approach in over a decade.

Over the past several weeks, both worlds have been slowly converging and on June 30, and July 1, they will reach their tightest grouping, separated by less than half a degree.

The distance between the planets will be so minute that onlookers will be able to cover both planets with just their pinky held at arm’s length.

The celestial meetup known as conjunction is the second in a series of three between Venus and Jupiter in over a year.

Even though conjunctions are not that rare, this particular series between the cosmic duo is the best in about 15 years.

Historically Venus and Jupiter conjunctions may be a possible answer to the Star of Bethlehem legend.

In the years 2 and 3 B.C., there was a similar series of three stunningly close pairings between the planets that would have caught the eye of ancient astronomers.

The best bet to catch sight of the pretty pairing is to look westward and high in the sky beginning a half hour after local sunset.

As darkness falls, beacon-like Venus will make its appearance first. Both planets shine so brilliantly, that observers should have no problem spotting them at dusk.

Venus will appear about 6 times brighter than Jupiter even though it’s only a tenth the size.

That’s because Venus is eternally enshrouded with highly reflective white clouds and is much closer to Earth. It’s about 56 million miles (90 million kilometers) away while Jupiter is much more distant—some 550 million miles (890 million kilometers).

Hence, their apparent proximity to each other is just an optical illusion.

You will be able to spot Venus’s disk, which resembles a miniature version of a quarter moon with even the smallest of backyard telescopes.

With Jupiter, high magnification will showcase its dark cloud belts and four of its largest moons, sitting beside the planet like a row of ducks.

Both planets will be lost in the glare of the sunset by the end of the month and will reappear in late August as bright morning stars visible before dawn.

However, Venus and Jupiter will offer one last opportunity for an amazing photo at dusk.

As a grand finale, the planets will be joined by the razor-thin crescent moon on July 18th.

This offers a perfect opportunity for night sky lovers to catch the three brightest nighttime celestial objects huddled together, all in the same field of view.

Jupiter’s Great Red Spot grows taller: NASA

Jupiter's Great Red Spot, which has been shrinking for a century and a half, seems to be growing taller as it gets smaller

Jupiter’s Great Red Spot, which has been shrinking for a century and a half, seems to be growing taller as it gets smaller, NASA scientists have found.

The Great Red Spot is a persistent high-pressure region in the atmosphere of Jupiter, producing an anti-cyclonic storm 22 degree south of the planet’s equator.

The findings, published in the Astronomical Journal, indicate that the Great Red Spot recently started to drift westward faster than before. Historically, it’s been assumed that this drift is more or less constant.

The study confirms that the storm has been decreasing in length overall since 1878 and is big enough to accommodate just over one Earth at this point. But the historical record indicates the area of the spot grew temporarily in the 1920s.

“Storms are dynamic, and that’s what we see with the Great Red Spot. It’s constantly changing in size and shape, and its winds shift, as well,” said Amy Simon, an expert in planetary atmospheres at NASA’s Goddard Space Flight Centre in Maryland.

“There is evidence in the archived observations that the Great Red Spot has grown and shrunk over time,” added Reta Beebe, Professor at New Mexico State University in Las Cruces. “However, the storm is quite small now, and it’s been a long time since it last grew,” Beebe said.

Because the storm has been contracting, the researchers expected to find the already-powerful internal winds becoming even stronger. However, instead of spinning faster, the storm appears to be forced to stretch up. The change in height is small relative to the area that the storm covers, but it’s still noticeable.

Further, the Great Red Spot’s colour is also deepening, becoming intensely orange since 2014, the researchers observed. While the researchers are not sure why that’s happening, it’s possible that the chemicals which colour the storm are being carried higher into the atmosphere as the spot stretches up.

At higher altitudes, the chemicals would be subjected to more UltraViolet radiation and would take on a deeper colour. Once big enough to swallow three Earths with room to spare, the mystery surrounding Great Red Spot seems to deepen as the iconic storm contracts.

Researchers do not know whether the spot will shrink a bit more and then stabilise, or break apart completely. “If the trends we see in the Great Red Spot continue, the next five to 10 years could be very interesting from a dynamical point of view,” the researchers said.

“We could see rapid changes in the storm’s physical appearance and behaviour, and maybe the red spot will end up being not so great after all,” they added. IANS
