当時、ビデオゲームの色数が豊かになってきていて、特に鋭角なキャラクターを描くのに高解像度で色数が少ないのと低解像度で色数が多いのとどちらが適しているかという話題があった

[うにゃ @Wu_Niang]

PC-8801（俺はmk-IIだった）は640*200画素3bit色深度のクソデジタル8色しかだせないという、グラフィクスが非力なパソコンだったけど、2*2のサブピクセルに見立てたら125色は表現できたんだよ。高2のとき着想したんだけど、アドベンチャーゲームの一部はこれ使ってた。
そんなことも青春の思い出。

[MASA Planetary Log @MASA_06R]

これ応用すればPC88風（デジタル8色または9ビットアナログカラー512色中8色、ドット縦横比2:1）も可能ですかね！？

[魔王源 @_maogeng]

PC98っぽい画像を生成できるプロンプトを作ってみた。
どこにニーズがあるかはわからん。たぶんおじさん向けだ！！

[MASA Planetary Log @MASA_06R]

一度単色で塗り分けてからタイリングで塗り直していくプロセス、よく考えたなと思いましたね。（そうしないとタイリングに使われている色で領域が混乱する）

[チャンス加藤 @chancekato1]

で、結局はLINE&PAINTで半自動で描かせるという「40年以上前のテクノロジー」が楽しくて、また一枚描いてしまった。
（でも85～86年ってグラフィックツールも出回ってたし、あまりメジャーな描き方じゃなかったかも）

JUST IN: intensifying sunspots AR 4455 erupted an Earth-directed M9.3 flare.

The M9.33 eruption peaked at 01:36:00 GMT on 03 Jun 2026.

[Edward.Vijayakumar @edwanx]

AR4455 produced another strong M7.7 flare with a stunning eruption. The associated CME is directed mainly northward. Glancing impact possible.

Astronomers have found the strongest evidence so far that some planets outside the Solar System possess magnetic fields.

The study focuses on seven ultra-hot Jupiters, giant gaseous exoplanets orbiting extremely close to their stars, with one side permanently facing the star and the other locked in darkness.

These planets are not Earth-like and are not candidates for life, but their atmospheres offer a useful laboratory because they are hot enough for metals such as iron to become detectable and partly ionized.

Using high-resolution observations from instruments including ESPRESSO on ESO’s Very Large Telescope and MAROON-X on Gemini North, the team measured Doppler shifts in iron lines to estimate atmospheric wind speeds.

Under ordinary atmospheric physics, hotter planets should have stronger winds because their atmospheres receive more stellar energy. Instead, the researchers found the opposite trend: the hotter the planet, the slower the measured winds.

The most plausible explanation is magnetic drag. In these intensely heated atmospheres, charged particles interact with the planet’s magnetic field, which acts like a brake on atmospheric circulation. From this relationship, the team inferred magnetic field strengths of at most a few gauss, broadly comparable to magnetic fields found among Solar System planets and close to Jupiter-like values.

The result does not mean that Earth-like exoplanets with protective magnetic fields have been detected. It means that, for the first time, astronomers have a robust population-level method for linking atmospheric dynamics to planetary magnetism in exoplanets.

That matters because magnetic fields can influence how planets evolve, how their atmospheres are retained or lost, and, indirectly, whether rocky planets might remain habitable over long timescales.

爆発する細胞死の発見
https://t.co/XqaZV0sMk3

プラナリアにおいて、自爆・破裂して、周囲の細胞や細菌を数分で殺す新しい細胞死を発見💣️
破裂を表す"rupt"から、その細胞死をruptosisと命名。

ruptosisを引き起こす分子を特定した一方、周囲を殺す毒性因子は未解明。今後の研究が楽しみです🔍️

アニメ映画のTV放映は、もはやEテレが最後の砦になってきたな。
ノーカット・ノーCM・余計な番組中企画なし・全国同時放映。まさにTV放映の理想形！

NHK総合での「この世界の片隅に」放映、今回の「マイマイ新子と千年の魔法」放映と来たら、次はぜひ「アリーテ姫」の放映も企画してほしいな。

Some LC-36 updates. Now that we’ve had access to the pad and integration facility we can share a bit of good news. The propellant farm, oxygen, liquid hydrogen and LNG tanks are all in good shape. This is good luck because these are very long lead items. The water tower is also good. The big support tower is damaged, but it can be repaired in place rather than torn down and replaced. The booster “Never Tell Me The Odds” and the three GS-2s that were onsite in the integration facility also look good.

I’ve seen some speculation that we might move directly to the 9x4 configuration, but we won’t do that. Rate manufacturing of 7x2 is going well, and we’re going to continue that at pace as planned and store the stages for use. In addition, we had already been working for some time on eliminating our transporter-erector in favor of an alternative vertical conop, and we’ll now go directly to that; so we don’t need a new transporter-erector.

We will fly again before the end of this year. Gradatim Ferociter.

Latest LASCO C2 images with GOES X-ray light curves from https://t.co/n4ruBjB4pl. See how the intense flares in AR 14455 were associated with CMEs. Note that the prominent CME shortly after the M3.3 flare (around 2026/06/02 17:00) was from a different eruption on the east limb.
