Perseid Meteor Shower

Every 133 years or so, the massive Swift-Tuttle comet careens through our solar system at 150 times the speed of sound, spreading a dirty trail of ice, dust and sundry space schmutz behind it. This weekend, Earth will do its part to clean up that interstellar mess during an annual event we call the Perseid meteor shower.

The Perseids occur every year from mid-July to late August, when Earth passes through the wide band of debris left behind by Comet Swift-Tuttle’s various visits to our part of the galaxy. Each time the comet swings by (most recently in 1992), it drops trillions of tiny pieces of itself into our inner solar system. Most of these little specks of metal and stone are as small as grains of sand, but that doesn’t prevent them from flashing across the night sky when they collide with Earth’s atmosphere at about 133,200 mph (214,365 km/h).

The resultis one of the most dazzling meteor showers of the year — and the best time to watch it is this weekend. On Sunday night (Aug. 12) and into early Monday morning (Aug. 13), Earth will push through the densest band of the Swift-Tuttle debris cloud that our planet has access to.

Drought in El Salvador

In El Salvador, there will be a meeting of the United Nations country team tomorrow [27 July] to develop a plan of action following the declaration by the Government of a red alert emergency due to the severe drought affecting some 77,000 corn farmers. Lack of rain led to losses of over 90,000 metric tons of corn, one of the main staple foods in the country. The eastern part of the country has reported 33 consecutive days without rain and record temperatures reaching 41°C.

In the Amazon, when turtles weep, butterflies drink. This image shot in the Peruvian Amazon shows an astonishing sight: colorful butterflies drinking tears directly from the eyes of turtles basking by the river.

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.
