Partial lunar eclipse Aug. 27-28 live updates — tonight is the night!

Source: Space.com

Level

A rare and deep partial lunar eclipse occurred on the night of August 27–28, capturing the attention of skywatchers worldwide. At the moment of maximum eclipse, 96.2% of the moon slipped into Earth's dark central shadow, known as the umbra. Much of the lunar disk took on a striking rusty red hue, while only a thin sliver remained brightly lit. This event was the deepest partial lunar eclipse visible anywhere on Earth until December 31, 2028.

The eclipse came remarkably close to producing a total lunar eclipse, or 'blood moon,' making it a must-see celestial event. Observers were advised to stay up late or set an early alarm to catch the phenomenon at its peak. The alignment of the sun, Earth, and moon created an almost-blood-moon spectacle. Eclipse enthusiast and journalist Daisy, who had previously witnessed a total lunar eclipse from a beach in Barcelona, described August's event as an incredible show.

For those who missed the August eclipse, the next lunar eclipse will occur on the night of February 20, 2027. However, this will be a subtle penumbral eclipse, in which the moon passes only through Earth's faint outer shadow. The darkening will be barely noticeable, peaking at 6:12 p.m. EST. The next truly dramatic lunar eclipse — a full blood moon — will not happen until New Year's Eve 2028, visible across Asia, Australia, and the Pacific.

Throughout history, lunar eclipses have inspired awe and fear in cultures around the world. Ancient Mesopotamians believed a lunar eclipse threatened their king and would literally hide him to protect against perceived danger. The Inca interpreted the moon's reddening as a great predator attacking the lunar disk, and would make loud noises and set their dogs barking to frighten the creature away. Today, science explains the eclipse as a spectacular consequence of orbital mechanics.

Photographers captured stunning images of the August eclipse as Earth's shadow swept steadily across the Sturgeon Moon, turning it a deep crimson at maximum eclipse. The colossal curve of our planet's silhouette was dramatically visible as it consumed nearly the entire lunar disk. As the eclipse wound down, the shadow gradually retreated, restoring the moon's usual brilliance. A photo wrap of the most breathtaking images was compiled to celebrate the event.

Japanese translation

8月27日から28日にかけて、希少な深い部分月食が発生し、世界中の天文ファンの注目を集めた。最大食の瞬間には、月の96.2%が地球の本影に入り込み、月面の大部分が赤錆色に染まった。わずかな細い弧だけが明るく輝き続けた。この部分月食は、2028年12月31日まで地球上のどこからも見られる最も深いものだった。

今回の月食は皆既月食「ブラッドムーン」に非常に近い現象で、見逃せない天文イベントとなった。ピークを観測するために夜更かしや早起きが推奨された。バルセロナのビーチで皆既月食を体験したことのある天文ライターのデイジーも、8月の月食は圧巻のショーだったと語った。

8月の月食を見逃した人にとって、次の月食は2027年2月20日夜に発生する。しかしこれは地球の外側の半影を月が通過するだけの半影月食で、暗くなる程度はわずかだ。次に劇的なブラッドムーンが見られるのは2028年の大晦日で、アジア・オーストラリア・太平洋地域で観測できる。

歴史的に、月食は世界各地の文化で畏怖や恐怖の対象となってきた。古代メソポタミア人は月食が王に危険をもたらすと信じ、王を隠した。インカの人々は月が赤くなるのを天敵が月を襲ったためと解釈し、大声を上げたり犬を吠えさせたりして追い払おうとした。現代では科学が軌道力学の壮観な結果として解明している。

8月の月食では、地球の影がスタージョンムーンをゆっくりと覆い、最大食の瞬間に月が深い深紅色に染まる様子を写真家たちが見事に捉えた。惑星規模の弧が月面の96%近くを呑み込む圧倒的な光景が記録された。その後、影は徐々に後退し、月は通常の輝きを取り戻した。

Laser-wielding mosquito killer hits market promising to track and zap backyard pests midair

Source: Fox Business

Level

A Chinese startup called Photon Matrix has launched a high-tech mosquito elimination device that uses laser technology to track and destroy mosquitoes in mid-air. The indoor version of the system is priced at $988, while the outdoor blue laser model starts at $1,088. The company claims the device combines lidar, radar, and AI vision to detect and precisely target individual mosquitoes before firing a precision laser, offering a futuristic alternative to conventional bug zappers.

The outdoor unit is designed for use on patios, campsites, and outdoor dining areas. It scans a 20-foot, 90-degree field in front of the device and can detect insects as small as 2 millimetres moving at speeds of up to 3.3 feet per second. A rotating base extends coverage to a full 360 degrees. The unit can operate for approximately four to five hours on a portable power bank, offering flexibility for outdoor settings without a fixed power source.

Photon Matrix says its system evaluates each detected object's size and shape before firing, ensuring the laser only targets mosquitoes and not other flying insects such as butterflies. The device measures the distance to a solid background before each shot, and automatically shuts off if no solid background is detected within range, a safety feature designed to prevent unintended laser exposure. The indoor model uses invisible infrared laser technology suited for bedrooms and hotel rooms.

The company emphasises that the device operates without chemicals, is controllable via a smartphone app, and is marketed as safe for both children and pets. Photon Matrix also provides a 12-month warranty. Online commentary has been enthusiastic, with social media users dubbing the product an 'Iron Dome for mosquitoes' and praising its reported ability to lock onto a target in just three milliseconds. These performance claims, however, come solely from the manufacturer.

The timing of the product launch aligns with growing public concern over mosquito-borne illnesses. Health officials in Nashville recently detected West Nile virus in a local mosquito pool, highlighting the ongoing health risks posed by the insects. Airport workers in a major travel hub have also died following malaria cases, drawing renewed attention to the dangers of mosquito transmission. Whether Photon Matrix's laser system delivers on its bold promises remains to be seen, but it has already generated significant buzz.

中国のスタートアップ企業フォトン・マトリクスが、空中の蚊をレーザーで追跡・撃退するハイテク装置を発売した。室内用モデルは988ドル、屋外用の青色レーザーモデルは1,088ドルから。同社は、ライダー・レーダー・AI視覚を組み合わせて蚊を個別に検出し、精密レーザーで仕留めると説明しており、従来の殺虫ランプに代わる未来的な選択肢を提案している。

屋外用ユニットはパティオやキャンプ場、屋外ダイニングでの使用を想定しており、前方20フィート・90度の範囲をスキャンし、時速3.3フィートで移動する2ミリメートルの昆虫まで検出できる。回転式台座により360度のカバレッジを実現。ポータブルバッテリーで約4〜5時間稼働するため、電源のない屋外でも柔軟に使用できる。

フォトン・マトリクスは、検出した物体のサイズと形状を評価してから発射するため、蝶などの他の昆虫には反応しないと説明している。また発射前に背景までの距離を計測し、背景が検出できない場合は自動的にレーザーを停止する安全機能も搭載。室内モデルは人の目に見えない赤外線レーザーを採用し、寝室やホテルに適している。

同社は化学物質不使用、スマートフォンアプリでの操作、子供やペットへの安全性を強調し、12ヶ月保証も提供している。SNS上では「蚊版アイアンドーム」と称され、3ミリ秒で蚊を捕捉するとして話題を呼んでいる。ただし、これらの性能に関する主張はすべてメーカー自身によるものだ。

製品発売の時期は、蚊が媒介する感染症への社会的関心の高まりと重なっている。ナッシュビルでは蚊のプールからウエストナイルウイルスが検出され、主要空港では空港職員がマラリアで死亡する事態も起きている。フォトン・マトリクスのレーザーシステムが約束を果たせるかは未知数だが、すでに大きな注目を集めている。
