There was a prospect that the iPhone 15 could be released in a gorgeous pink color.

According to foreign media, there was light pink in the series before the iPhone 15, but there was no flashy pink.

This iPhone 15 is expected to be released in green and yellow, including gorgeous pink. Looking at the iPhone 15 Pro model color outlook, the iPhone 15 series colors can also be released in red, starlight, and midnight colors.

Looking at the iPhone 14 color lineup, there were blue, purple, and dark yellow. If the iPhone 15 color forecast is correct, the colors that were seen on the iPhone 14, such as blue, purple, and dark yellow, cannot be seen on the iPhone 15.

It’s been a year since the James Webb Space Telescope (JWST; Webb) released four pictures to the public.

During the 12 months that the Web published the photos, the general public was amazed at their ability to capture even the tiniest of light, and the scientific community cheered for an unexpected discovery.

On the 12th (local time), the American media Business Insider compared and analyzed the astronomical photos taken by Webb with those taken by Hubble, a space telescope, in celebration of the first anniversary of the release of Web photos.

Rings of Uranus… Web caught 11 in just 12 minutes

In April, the National Aeronautics and Space Administration (NASA) released new photos of the icy planet Uranus in the solar system.

Farrani’s glowing Uranus was similar to the one taken by Hubble, but above all, attention was drawn to the sharp rings surrounding it. Although Uranus has rings like Saturn, it is difficult to capture with a space telescope because it is made of rock and dust that does not reflect sunlight.

In 1986, NASA’s Voyager 2 probe and the Keck Observatory teamed up to discover the first two rings, but this was due to Voyager 2’s proximity to Uranus.

Hubble also photographed the two outermost rings in 2022, but Webb clearly captured 11 of the 13 rings in just 12 minutes of filming.

Sharp infrared eyes to Jupiter auroras and storms

Last August, Webb set his sights on Jupiter, the largest planet in the solar system.

The Great Red Spot, a giant storm, and the streaks across the planet were as known to mankind, but the polar regions were different.

Webb’s image of Jupiter shows its poles glowing. Jupiter, which has a magnetic field 20,000 times stronger than Earth’s, produces the most powerful auroras in the solar system.

On the other hand, the reason why Jupiter, which had only been seen in ocher color, appeared blue to Webb’s eyes was not in visible light like Hubble’s, but because it synthesized three pictures taken with a near-infrared camera (NIRCam) with three special infrared filters of red, yellow-green, and blue. .

The Southern Ring Nebula “really had two stars in the center”

The Southern Ring Nebula, also known as the Eight-Burst Nebula, was one of the first images published by Webb on July 12 last year.

In the Southern Ring Nebula, a dying star continues to ripple and push dust outward. Scientists knew there were two stars at the center of the nebula, but to Hubble the single star appeared like a small dot.

However, when observed through the web, two stars in the center of the nebula clearly shined. Also nearby were three stars shining in a nebula. Even the long-gone light was captured by Webb’s sharp eye.

The ‘Scattering Field of Stars’ reveals the true value of the web

Webb’s sharp field of view can be confirmed when shooting the so-called ‘star scattering field’ where new stars are born.

Stars are usually born surrounded by a thick layer of cosmic dust and gas, and the webs penetrate this thick ‘cocoon’ and capture even faint light clearly.

This can be seen in the Carina Nebula. The Carina Nebula was also included in the first picture released last year. In particular, the upper left of the image is where young stars are forming. Numerous stars that were invisible when taken by Hubble have made their presence felt in images from the Web.

In 20 hours, to the distant light hidden in a black space

Deep field, one of the first five chapters published by Webb. This deep field, Hubble’s first attempt, refers to taking pictures of outer space where nothing can be seen.

The Ultra Deep Fields, taken in 2003 and 2022 by Hubble and Webb, respectively, look similar at first glance. However, it made a huge difference in time. These huge space telescope projects are literally ‘time is money’. An astronomical amount of money goes into operating it for just one day.

In 2003, Hubble took just 11.3 days to complete this image. It was obtained by taking 800 images during Hubble’s 400 orbits around the Earth. On the other hand, Webb proved its performance by taking photos that surpassed those of Hubble in just 20 hours.

“A giant asteroid is about to pass Earth at close range”

An excited festive atmosphere is created in anticipation of a splendid space show that will unfold as meteor showers pass by all over the world. A report warning of a meteorite collision is issued from the space station Mir, which was tracking the orbit of an asteroid group, but it is dismissed as an unlikely event on Earth. The force of meteorite fragments in the blind spot behind the asteroid is 10 times that of a nuclear bomb. Destroying the space station and eventually collapsing buildings and roads by asteroids heading for Earth, a catastrophe unfolds.

Planet, produced by the Russian Federation, is a science fiction (SF) disaster film with the theme of an asteroid impact. The story unfolds between the destroyed space station and the devastated earth after the fall of the meteorite. All over the world, including Australia, New Zealand, Okinawa, Primorskiy, and Korea, suffered great damage from meteorites, and depicted urban infrastructures collapsing and turning into ruins in a realistic way.

An asteroid is a celestial body that orbits the sun smaller than a planet orbiting inside the orbit of Jupiter. In contents such as movies, novels, cartoons, and games set in the universe, it is a regular material that appears as a threat that can destroy the earth and a pioneering target rich in rare resources. A meteorite is a generic term for rocks that fall to the Earth’s surface from space, including asteroids.

An asteroid impact is a real threat, not just science fiction. On June 30, 1908, a 40 to 50 m class asteroid fell in the Tungska region of Russia, knocking down 80 million trees within a distance of 25 km and devastating Siberian forests. In order to raise awareness about the risk of asteroid impact and to respond internationally, the United Nations (UN) designated this day in 2016 as ‘World Asteroid Day’.

Relatively recently, in 2019, an asteroid with a diameter of 57 to 130 m, named ‘Asteroid 2019 OK’, narrowly missed the Earth at 24 km per second. At that time, the distance the asteroid passed was only 1/5 of the distance between the Earth and the Moon. The existence of Asteroid 2019 OK was only noticed on Earth a few hours prior to the nearest point in time.

Like the asteroids in the movie Planet, when an asteroid with a diameter of more than 100m collides with the Earth, a city is razed to the ground. If the diameter exceeds 1 km, the Earth’s ecosystem cannot recover. The National Aeronautics and Space Administration (NASA) is monitoring about 2,300 ‘potentially dangerous asteroids (near-Earth asteroids)’ with an orbit within 750 km from the Earth and a size of more than 140 m.

A defensive strategy to protect Earth from asteroids is also being envisioned. Last year, the United States conducted an experiment to change the trajectory by crashing a spacecraft into an asteroid. By using the spacecraft as a kinetic impactor and accurately colliding with an asteroid with a diameter of 160 m, it is expected to shorten the asteroid’s orbital period by about 1%. Directly blowing up an asteroid with a nuclear bomb in outer space is also being discussed, as in Michael Bay’s 1998 film Armageddon.

The scientific community considers the possibility of an asteroid larger than 140 m colliding with the Earth within 100 years as low. However, the universe is still an unknown territory for mankind. Efforts to prepare for unexpected cosmic threats must continue.
