1st known ‘Trojan’ planets discovered locked in the exact same orbit around a star
Astronomers have discovered the first evidence of ultra-rare ‘Trojan’ planets: two sibling planets bound on the same orbit around the same star.
The potential co-orbiting planets, dancing around the young star PDS 70 roughly 370 light-years away, consist of a Jupiter-size planet and a cloud of debris — possibly the shattered remains of a dead planet, or the gathering building blocks of one yet to be born.
Lagrange points are places in a solar system where the gravitational pulls of a star and an orbiting planet balance out the motion of an object’s orbit, trapping the object so that it moves in lock-step with the planet.
It takes a quadrillion years for a white dwarf to crystallize, and since the Universe is not even 14 billion years old, astronomers will never spot a fully crystallized one. But this research removes some of the mystery by finding one that’s just starting to become a cosmic diamond. Curious astronomers will study more of these bizarre stellar remnants, and one day, we may know exactly how and when something so strange can happen.
A skyscraper-size asteroid flew closer to Earth than the moon — and scientists didn’t notice until 2 days later
Now dubbed 2023 NT1, the roughly 200-foot-wide (60 meters) space rock sailed past our planet on July 13, traveling at an estimated 53,000 mph (86,000 km/h), according to NASA. However, because the rock flew toward Earth from the direction of the sun, our star’s glare blinded telescopes to the asteroid’s approach until long after it had passed.
Astronomers didn’t catch wind of the building-size rock until July 15, when a telescope in South Africa — part of the Asteroid Terrestrial-impact Last Alert System (ATLAS), an array of telescopes designed to spot asteroids several days to weeks before any potential impact — caught the rock making its exit from our neighborhood. More than a dozen other telescopes also spotted the rock shortly afterward, according to the International Astronomical Union’s Minor Planet Center.
Hundreds of ‘ghost stars’ haunt the Milky Way’s center. Scientists may finally know why
“Planetary nebulas offer us a window into the heart of our galaxy and this insight deepens our understanding of the dynamics and evolution of the Milky Way’s bulge region,” University of Manchester astrophysicist Albert Zijlstra said in a statement.
Studying 136 planetary nebulas in the thickest part of the Milky Way, the galactic bulge, with the Very Large Telescope (VLT), the team discovered that each is unrelated and comes from different stars, which died at different times and spent their lives in different locations.
The researchers also found that the shapes of these planetary nebulas line up in the sky in the same way. Not only this, but they are also aligned almost parallel to the plane of the Milky Way.




In the annals of 1950s cheesy paperback covers, surely Man of the World should feature somewhere. The sell line (“He wanted her for things money couldn’t buy”) drips innuendo, without actually saying anything. The babe on the cover is sultry. The promise that it’s “complete and unabridged” suggests that there are naughty bits that a more timid publisher might have expurgated. I found nothing that by current standards would be considered naughty.
When my parents met my father was married to a woman named Kit, who was a model, Vogue Magazine beautiful, and apparently a… difficult person. According to the novel, the protagonists (Nick and Delia) have a rather chaste thing going on–she lives with her mother, as my mother did–and they go to the movies or out to dinner. Early on in the book she decides this is going nowhere, and moves to New York. Okay, so far it jibes with family lore. My mother moved to New York and lived in a walk-up over a men’s haberdashery across 6th Avenue from the Women’s House of Detention on 9th Street. My father moved back to New York, having split with the beautiful Kit. He had an apartment-and-studio on 11th Street. Somehow they got back together. 
I love to “talk shop” with other writers. I learn so much about my own process and my weaknesses because it’s always easier to see the flaws – and the strengths! – in someone else’s work. Recently, I had the mirrored experience of serving as a beta reader for another writer’s novel and receiving similar feedback on one of my own. The thematic similarities and differences between the two very early versions of the stories are irrelevant. What fascinated me was that we used dialog in diametrically opposed ways in our story construction: my friend’s rough draft read like a screenplay, and mine had comparatively little conversation. We’ll both end up with balanced manuscripts, but we’ve started from opposite places.
