Global Temperature Extremes

The week’s hottest temperature was 124 degrees Fahrenheit (51.1 degrees Celsius) in Death Valley, California.

The week’s coldest temperature was minus 111.0 degrees Fahrenheit (minus 79.4 degrees Celsius) at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

The Moons of Jupiter

While hunting for the proposed Planet Nine, a massive planet that some believe could lie beyond Pluto, a team of scientists, led by Scott Sheppard from the Carnegie Institution for Science, found the 12 moons orbiting Jupiter. With this discovery, Jupiter now has a staggering 79 known orbiting moons — more than any other planet in the solar system.

Record high temperatures around world this week

Record high temperatures have been set across much of the world this week as an unusually prolonged and broad heatwave intensifies concerns about climate change.

The past month has seen power shortages in California as record heat forced a surge of demand for air conditioners. Algeria has experienced the hottest temperature ever reliably registered in Africa. Britain, meanwhile, has experienced its third longest heatwave, melting the roof of a science building in Glasgow and exposing ancient hill forts in Wales.

The World Meteorological Organization (WMO) said the rising temperatures were at odds with a global cyclical climate phenomena known as La Niña, which is usually associated with cooling.

Taiwan is the most recent place to report a new high with a temperature of 40.3C in Tianxiang on Monday.

Total Full Moon Eclipse – Longest in 21st Century

A total full moon eclipse which will be viewable from multiple continents including most of Africa is happening on 27 July. This lunar eclipse will be primarily visible from the world’s Eastern Hemisphere (Europe, Africa, Asia, Australia and New Zealand).

The eclipse will take place at or around midnight for Madagascar and the Middle East. Europe and Africa will view it sometime between sunset and midnight on 27 July, whereas most of Asia, Indonesia and Australia will view it in the morning – sometime between midnight and sunrise on 28 July.

The eclipse, which will last for one hour and 43 minutes, will be the longest lunar eclipse of the whole 21st century.

Newborn planet pictured for first time

Astronomers have captured this image of a planet that’s still forming in the disk of gas and dust around its star.

Researchers have long been on the hunt for a baby planet, and this is the first confirmed discovery of its kind. Young dwarf star PDS 70 is less than 10 million years old, and its planetary companion is thought to be between five and six million years old.

Visitor from another solar system accelerated away from the Sun

Last year, the Solar System was treated to its first known tourist. ‘Oumuamua, an odd, cigar-shaped body, shot through our neighborhood at high speed, following an orbit that indicates it arrived from somewhere else. Although bodies ejected from other solar systems are expected to make regular visits, this was the first one that we’d imaged sufficiently to determine that its origins were elsewhere.

The imaging, however, didn’t resolve a somewhat different debate: what, exactly, is ‘Oumuamua? Its odd orbit had initially had it categorized as a comet, as these tend to have more extreme orbits. But imaging didn’t show any indication of gas and dust being released, as is typical when a comet approaches the Sun. That imaging also revealed that it had an elongated, cigar-like shape. Combined with its relatively rapid rotation, this would indicate that ‘Oumuamua had to be fairly robust, leading to the conclusion that it was probably an asteroid.

But now, a large international team of researchers is weighing in with another vote for comet. The argument, says the team, is based on the odd behavior of ‘Oumuamua, which appears to have been accelerating away from the Sun.

Scientists explain the acceleration to be caused by warming-induced gas release from particles on the body of the comet which appears to be the least-worst of the possible explanations. It should generate a consistent force and one that scales with proximity to the Sun, which is what seems to be happening.

Hottest Night in Recorded History

The day of June 26 was a scorcher in the town of Quriyat, Oman. Temperatures in the town, which is weathering a miserable heat wave, peaked at 121.6 degrees Fahrenheit (49.8 degrees Celsius) during the day, according to Weather Underground. That’s just shy of the Omani record-high temperature of 123.4 degrees F (50.8 degrees C), set on May 30, 2017. But anyone in Quriyat hoping for an evening respite from the extreme heat would have been disappointed: Temperatures fell to a low of just 108.7 degrees F (42.6 degrees C.) That’s a world record: The highest “low” temperature ever recorded in history.

Martian Sand Dune

A big sand dune blazes in an electric blue on the Red Planet in a gorgeous photo by NASA’s Mars Reconnaissance Orbiter (MRO).

The large, complex dune is embedded within a field of classic, crescent-shaped dunes on the floor of the 147-mile-wide (236 kilometers) Lyot Crater, which lies about 50 degrees north of the Martian equator.

“This particular dune, appearing like turquoise blue in enhanced color, is made of finer material and/or has a different composition than the surrounding” sand, NASA officials.

The Coldest Place on Earth Is Even Colder

Scientists already knew that the lowest temperatures ever measured on Earth were on a frozen ice ridge in eastern Antarctica, near the South Pole. But they recently discovered that temperatures there can drop even lower than those previously measured.

In 2013, analysis of satellite data pinpointed scattered pockets of intensely cold air on the East Antarctic Plateau between Dome Argus and Dome Fuji — temperatures that dipped to a staggering minus 135 degrees Fahrenheit (minus 93 degrees Celsius).

However, new analysis of the same data suggests that under the right conditions, those temperatures can drop to nearly minus 148 degrees F (minus 100 degrees C), which is probably the coldest it can get on Earth, researchers reported in a new study.
