Mars is still an active world—here’s a landslide in Nili Fossae
Since the 1960s and ’70s, scientists have come to view Mars as something of a “dead planet.” As the first close-up images from orbit and the surface came in, previous speculation about canals, water and a Martian civilization were dispelled. Subsequent studies also revealed that the geological activity that created features like the Tharsis Mons region (especially Olympus Mons) and Valles…
A new record for the most distant quasar
Astronomers have a new measurement for the distance of quasar J0313-1806, making it the new record-holder for the most distant quasar known. We’re seeing it just 670 million years after the Big Bang, or more than 13 billion light-years away. Source: https://earthsky.org/space/new-record-most-distant-quasar-black-hole-j0313-1806…
The Impractical but Indisputable Rise of Retrocomputing
For all the personal technology introduced and popularized in 2020 — upscale fitness bikes, at-home Covid tests, game consoles new and old — the personal computer lands on the list with a bit of a thud. PCs lack the novelty of other gadgets, but they’re practical, essential even, in a year when work, school and social life have come to rely…
When will the Age of Aquarius begin?
Astronomers and astrologers may agree that the Age of Aquarius starts when the vernal equinox point moves out of constellation Pisces and into Aquarius. But when will that be? There’s no definitive answer. Source: https://earthsky.org/human-world/when-will-the-age-of-aquarius-begin…
Remembering the Golden Age of Computer User Groups
Slashdot reader #16,185 wrote regularly for the newsletter of a small-town computer users group. Now they’ve written an article for Ars Technica reminding readers that “The Homebrew Computer Club where the Apple I got its start is deservedly famous — but it’s far from tech history’s only community gathering centered on CPUs.” Throughout the 70s and into the 90s, groups around…
Terry Pratchett’s Earliest Stories To Be Published In September
Long-time Slashdot reader sjritt00 writes:
A final collection of Terry Pratchett’s early stories will be published in September as The Time-Travelling Caveman. These stories appeared in the Bucks Free Press and Western Daily Press in the 1960s and early ’70s and introduce many of the themes which later power his Discworld series. The Guardian reports that the stories “range from a steam-powered…
The Uncertain Future of Ham Radio
Julianne Pepitone from IEEE Spectrum writes about the uncertain future of ham radio. An anonymous reader shares an excerpt: Will the amateur airwaves fall silent? Since the dawn of radio, amateur operators — hams — have transmitted on tenaciously guarded slices of spectrum. Electronic engineering has benefited tremendously from their activity, from the level of the individual engineer to the entire…
CNET Remembers 1995, the Year Hollywood Finally Noticed The Internet
CNET is celebrating its 25th anniversary with articles remembering the 1990s — including that moment “when Hollywood finally noticed the web,” calling it “a flawed but fun snapshot of the moment the internet took over the world…” “Twenty-five years ago, cinema met cyberspace in a riot of funky fashion, cool music and surveillance paranoia. It began in May 1995 with the…
Cosmic quasars embrace 1970s fashion trend
Researchers from Russia, Germany, Finland and the U.S. have studied more than 300 quasars—spinning black holes that produce beams of plasma. The team has found that the shape of these so-called astrophysical jets changes from parabolic to conical at some distance from the black hole, reminiscent of the iconic flared jeans of the ’70s. By effectively measuring these “cosmic pants,” the…
