The week’s hottest temperature was 122 degrees Fahrenheit (50.0 degrees Celsius) in Mitribah, Kuwait.

The week’s coldest temperature was minus 102.0 degrees Fahrenheit (minus 74.4 degrees Celsius) at Russia’s Vostok base, Antarctica.

Perseid Meteor Shower

It’s that time of year again, when the spectacular Perseid meteor shower rains fire across the night sky. The days-long fireball fiesta is expected to peak this evening with an estimated 80 shooting stars per hour at its height. Widely seen as one of the most entertaining celestial events of the year, the Perseids meteor shower is caused by meteoroids from the debris trail of the Comet 109P/Swift-Tuttle which orbits the sun once every 133 years.

Those in the Northern Hemisphere will be treated to the best views, provided they can escape the light pollution from towns and cities. The moon will frustrate proceedings somewhat as a full moon is due on Thursday, meaning the sky will likely be washed out for the majority of viewers, but fear not, as the Perseids have an ace up their sleeve. Instead of shooting stars, stargazers can hunt for bright ‘fireballs’ which can last up to a second rather than merely fractions of a second like their shooting star brethren.

Close Call

Scientists revealed an asteroid dubbed by some as a “city killer” came closer to the Earth than the moon this week. The Washington Post reported that scientists apparently had no idea it was coming.

Asteroid 2019 OK came hurtling toward Earth at a speed of nearly 15 miles a second, before flying past. According to NASA, it was about 45,000 miles from Earth on Thursday.

Space Events

Delta Aquariid Meteor Shower

The dazzling Delta Aquariids 2019 meteor shower will be at its nominal peak tonight, July 29, and can be best spotted in the Southern Hemisphere.

What is essentially a display of space dust and bits of debris bursting from a comet (or comets) in our orbital path, the Delta Aquariids meteor shower will fly close to the Sun shedding particles that hit our atmosphere, around 60 miles above Earth. The meteor will zoom across the skies during which it will vapourize into shooting stars, leaving a trail of blazing light behind.

If at all you miss the celestial show tonight, you have until mid-August to catch the Delta Aquariid as the long, rambling meteor shower is officially active from July 12 to August 23 each year.

A recent sunset photo stunned viewers. An unusual optical effect made the sunset resemble a split-screen image showing two very different skies side by side.

Though it looks unnatural, the so-called split sunset wasn’t created with filters or Photoshop. Rather, it was caused by the shadow of a large cloud below the horizon that prevented sunlight from striking the clouds that were closer to viewers on the ground. The photo was shot in Charlotte, North Carolina, USA.

Ghostly Blue Clouds

It looks like a ring of blue fire in the sky. But, in fact, that swirl of sapphire over the North Pole and Greenland is actually ice — that, and a bit of pulverized meteor dust.

They’re called “noctilucent clouds,” because they only appear after sunset. Blue and wispy, these moonlighting cirrus strands form high in the atmosphere in spring and summer, when the upper atmosphere starts to cool as the lower atmosphere warms. There, ice crystals hovering about 50 miles (80 kilometers) over Earth glom onto little particles of dust from smashed-up meteorites and other windblown sources, then condense into smoky ribbons of cloud. (The same phenomenon has been spotted on Mars.)

These are the highest clouds in the sky,and form so high up that they glow icy blue even after the sun appears to have passed below the horizon at ground level. Usually, they’re only spotted at high latitudes in warm months; the ring of clouds above, shown in a composite image taken by NASA’s Aeronomy of Ice in the Mesosphere (AIM) spacecraft — a satellite that measures how much sunlight is being reflected into space by high-atmosphere clouds — appeared over Greenland on June 12, 2019.
