Astronomers using the Green Bank Telescope spotted surprisingly cold, dense hydrogen clouds embedded inside the Milky Way’s ...

RCS stands for Rich Communication Services, and is basically a souped up version of SMS: The platform supports modern messaging features, like typing bubbles, high-quality image and video sharing ...

Researchers have found clouds of cold gas embedded deep within larger, superheated gas clouds—or Fermi bubbles—at the Milky Way's center. The finding challenges current models of Fermi bubble ...

So when an iPhone user texted an Android user, the bubble turned green and you didn’t get those high-resolution images, you got these crummy-looking images because it reverted to SMS and MMS.

The gas bubbles, also known as convective granules, are about 621 miles (1,000 kilometers) across and move at speeds of a few kilometers per second, so they only survive for about 10 minutes.

While texting technology will soon get better, the “blue versus green bubble” disparity is far from over. By Brian X. Chen Brian X. Chen is The Times’s lead consumer technology writer and ...

With read receipts, high-res media, and more, RCS is almost as good as iMessage in iOS 18. But it’s still missing some features, and the implementation is a bit odd.
