Pluto’s atmosphere begins to freeze out as it drifts farther from the Sun

Astronomers report Pluto’s nitrogen-rich atmosphere is starting to freeze out as it moves away from the Sun, with atmospheric pressure dropping about 16% between mid-2021 and 2023. Pluto’s surface runs at roughly -382°F while the upper atmosphere sits around -333°F, conditions that favor frost formation as the air cools. Observations of ten stellar occultations from 2017–2023 show haze in the lower atmosphere settling toward lower latitudes as pressure falls. The findings, led by Amanda Sickafoose, suggest the atmosphere will not be fully frozen by aphelion (2114) but should rebuild somewhat as Pluto travels back toward the Sun. The study was published July 31 in the Planetary Science Journal.

Pluto's Atmosphere Freezes as It Moves Away from the Sun

Pluto’s nitrogen‑rich atmosphere is starting to condense into frost as it drifts farther from the Sun on its 248‑year orbit. Surface temperatures are about -382°F (-230°C) and the upper atmosphere around -333°F (-203°C). Observations of ten stellar occultations from 2017–2023 show atmospheric pressure has declined ~16% since 2021 (likely haze settling to lower latitudes). NASA’s New Horizons had measured a baseline atmospheric pressure of about 10 microbars in 2015. Pluto’s aphelion will occur in 2114 at ~49 AU, and the atmosphere isn’t expected to be fully frozen by then; frost could sublimate and the atmosphere thicken again as Pluto heads back toward the Sun.

FROST attack uses browser storage timing to fingerprint open sites and apps

Researchers describe FROST, a browser-based side-channel that measures SSD access latency via the origin private file system (OPFS) to infer which sites a user has open and which apps are running, enabling cross-site fingerprinting with no user interaction. The attack relies on large OPFS files and reads from the same SSD, limiting scale and making detection likely; mitigations include capping OPFS size or other browser changes. The work was demonstrated on macOS and is slated for presentation at the DIMVA conference.

Chilly Weather Ahead for Central and South Florida

Central Florida can expect a cool and breezy day on Monday with highs in the mid-60s, followed by a strong cold front bringing 30s and 40s temperatures early Tuesday. Patchy frost may occur north of Orlando, but widespread frost is unlikely due to the elevated breeze. Highs on Wednesday will reach the upper 50s, and a gradual warming trend is expected for the rest of the week. Thursday marks the first day of winter.

Chilly temperatures sweep through Florida as cold front arrives

The coldest day will be on Wednesday, with highs in the upper 50s to mid-60s and lows dropping into the 30s and 40s, potentially causing patchy frost in certain counties. However, temperatures will quickly bounce back into the upper 70s by the end of the week before another cold front arrives, potentially bringing strong to severe storms.

"Arctic Blast Brings Early Winter Chill Across the US"

A widespread cold snap is moving across the Lower 48, bringing the coldest air of the season so far. Many areas could experience their first frost or freeze, and several cities may break daily record lows, particularly on Wednesday and Thursday. The cold air is originating from a strong high-pressure system stretching from western Canada to the Plains, and it has already reached as far south as Texas and as far east as the Great Lakes. Frost and freeze alerts have been issued for parts of the Southwest, Midwest, Southeast, and interior Northeast, with more alerts expected. Over four dozen locations could be within a few degrees of daily record lows.
