On June 19, 2017, NASA’s Kepler space telescope team has released a mission catalog of planet candidates. The final catalog introduces 219 new exoplanet candidates, and 10 of them are near-Earth-size and orbiting their stars in the circumstellar habitable zone. Notes 1
This the eighth release of the Kepler candidate catalog. With this release, there are now 4,034 planet candidates (as of June 21, 2017) identified by Kepler space telescope, which launched by NASA on March 7, 2009, to discover Earth-size planets orbiting other stars. Of those, 2,335 have been verified as exoplanets. Of roughly 50 near-Earth size habitable zone candidates detected by Kepler, more than 30 have been verified. All the Kepler’s catalog is publicly available on NASA Exoplanet Archive.

Despite its unusual and a bit weird look, the AuthaGraph World Map may be the most accurate world map ever. It is created by the Japan artist and architect Hajime Narukawa, and won the Good Design Grand award in 2016.
Since the 16th century, we use Mercator Projection in most maps we used to seeing pinned on classroom walls and in Atlases – a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator (5 March 1512 – 2 December 1594) in 1569. It is very useful for ocean navigation since it preserves “true compass bearings between any two points”. But, it greatly distorts the shape of the lands. The closer the land to the poles of the Earth, the bigger it looks. For example, Greenland looks almost as big as Africa on a world map using Mercator projection, but actually, Africa is 14 times bigger than Greenland. Another example; Canada looks way bigger than the continental United States, but in fact, it is only about 1.2 times bigger.

Here are the top ten most powerful earthquakes (by the Moment magnitude scale, MMS; denoted as Mw or M) in recorded history, according to the United States Geological Survey (USGS), a scientific agency of the United States government.

Have you ever wondered what would Antarctica look like if all its ice melted? This may seem extraordinary and unlikely, but, this has actually happened in the past. In fact, there have been no major ice sheets over the South Pole for most of the Earth’s history.
In the video below, NASA Goddard strip away Antarctic ice to reveal a new, and much more detailed map of the bedrock below. This map, called Bedmap2, was compiled by the British Antarctic Survey and incorporates millions of new measurements, including substantial data sets from NASA’s ICESat satellite and an airborne mission called Operation IceBridge.

An international team led by the Italian photographer Filippo Blengini created a 365-Gigapixel Panorama of Mont Blanc, Europe’s highest mountain, and the gigantic image becomes the World’s largest photoSee Note. The previous record-holder, published in 2013, was a 320-gigapixel shot of London, taken from atop the BT Tower.
The huge image, published on the project’s site In2White, is created by stitching together 70,000 HD photos taken at 3,500 meters (11,483 feet). The shooting took 15 days in late 2014 and the average temperature was -10 °C (14 °F). The post-production took further two months.

We, humans, are changing our planet drastically that scientists say the world entered a completely a new geological era called “Anthropocene”. But, it seems we are not shaping only the surface and the atmosphere of Earth, human activities are changing our near-space environment as well. The change is so big that NASA’s Van Allen probes have detected a human-made barrier surrounding Earth.

Oymyakon, a village in Oymyakonsky Ulus of the Sakha Republic (Yakutia), the Russian Federation, is considered as the coldest inhabited place on Earth. On February 6, 1933, a temperature of −67.7 °C (−90 °F) was recorded at Oymyakon’s weather station. The village is considered as one of the Pole of ColdsNotes 1 of the northern hemisphere.

We see images and videos from the International Space Station (ISS) where astronauts floating in the space freely. That’s because they’re in the space, so there is no gravitational force of Earth there, right?
The International Space Station is in Low Earth OrbitSee notes 1 with an altitude of between 330 and 435 km (205 and 270 mi). It is so close to the Earth that on a clear day easily visible to the naked eye from the ground as it is the third brightest object in the sky (NASA has actually launched a new interactive map at its Spot the Station web site). At that altitude, the Earth’s gravity is about 90 percent of what it is on the planet’s surface – still pretty strong, right? To reduce the gravity of the Earth by a factor of one million, one needs to be at a distance of 6 million kilometers (around 3,728,227 miles) from the Earth – more than fifteen times the distance between the Earth and Moon.

Another unique and interesting friendship between a wild reptile and a man, like the famous story of Chito and Pocho. This Japanese man, named Nobumitsu Murabayashi, keeps a giant caiman as a pet, and even walks with him in the town center of Kure City, Hiroshima, Japan – with the permission of the city hall.

Ancient symbols carved into stone at Göbekli Tepe (an archaeological site in Turkey) tell the story of a big comet impact more than 13,000 years ago, scientists think. The devastating impact triggered a mini ice-age which drove many mammals weighing more than 40 kg to extinction.
According to an article published by New Scientist, carvings made on a pillar known as the “Vulture Stone” in Göbekli Tepe suggest that a swarm of comet fragments hit the Earth in around 11000 BC.
