| | Heat grips Pacific Northwest today to Monday | | | The U.S. National Weather Service has issued Excessive Heat Warnings and Watches - and Heat Advisories - across the western United States, including the entire state of Washington. Nearly 25 million people live in the region that will be affected, which includes the cities of Portland, Oregon; Seattle, Washington; and Vancouver, British Columbia.

People have been calling it a mega comet. It's thought to be the largest comet yet discovered. Its nucleus, or core, is between 62 to 230 miles (100 to 370 km) in diameter. Whoa! That's big, for a comet. It'll make its closest approach to us in 2031, sailing just outside of the orbit of Saturn.

Taupo has erupted less violently 28 times since then, with the largest and most recent of these events occurring in 232 CE. A new study published this month suggests that Taupo is active and potentially hazardous. It revealed that Taupo has an active reservoir of at least 60 cubic miles (250 cubic km) of magma beneath its caldera, with some 20-30% of this magma in a molten state. Read more. | | | | | | | |

Saturn isn't as bright as Jupiter (or the moon), but it's a glorious sight through a telescope. Watch for the moon and Saturn late tonight and Sunday morning, then keep watching to see the moon sweep past bright Jupiter. Read more. | | | | | |

 | | | Low-latitude noctilucent clouds in June 2021 | | View at EarthSky Community Photos. | Ben King in Israel captured this photo of noctilucent clouds on June 22, 2021. He wrote: “On my way to work, it’s usually dark, but these bright clouds above the horizon caught my eye. In disbelief, I thought they couldn’t possibly be noctilucent clouds. But they couldn’t really be anything else. I read many reports that there were record amounts of these clouds being seen at higher latitudes.” Thank you, Ben! Seeing noctilucent clouds - aka night-shining clouds - at southerly latitudes is rare. But - this month - we've been seeing photos of these clouds taken farther and farther south. Ben didn't say where he was in Israel, but the latitude of the northern edge of that country is about 33 degrees N. Learn more about noctilucent clouds, or clouds that shine at night. And watch for them! | | |
