We know that interstellar objects occasionally visit our solar system. So far, we have only discovered two interstellar objects (ISOs), but that’s mainly because we can only distinguish them from solar system bodies by their orbital motion, and that takes a series of observations over time. The two we have discovered, ?Oumuamua and Borisov, were only noticed because they had highly unusual orbits that moved through the inner solar system. But when sky survey telescopes such as the Vera Rubin Observatory come online, we will likely find new interstellar objects all the time. It’s estimated that several ISOs enter the solar system every year, and there could be hundreds of them passing by at any given time. But that raises an interesting question about how these objects arrive. Do they enter our solar system randomly from all directions, or do they appear in clusters a few at a time? That is the question addressed in a new paper on the *arXiv*. It looks at how streams of interstellar bodies might escape a solar system and how they would then move through the Milky Way. While it is always possible for a random asteroid or comet to have a random flyby near a large planet that tosses it out of a system, most interstellar bodies would occur during the tumultuous early period of a star system when it is cleared of debris. In our solar system this process created the Oort cloud surrounding the Sun, which likely occurred in other systems. So star systems likely create bursts of ISOs, which then stream through the Milky Way until they encounter another star system. Simulated streams of ISOs in the Milky Way. Credit: Forbes, et al To study all this, the team started with simulated bursts and then modeled how the resulting streams would evolve. Based on the distribution and typical ages of stars in our region of the Milky Way, they could then simulate streams that might intersect the Sun’s path through the galaxy. They found that the Sun likely intersects with streams regularly, which would give us plenty of interstellar visitors. They also found that just as Earth experiences meteor showers as it passes through the remnant debris streams of comets, the Sun would experience bursts of interstellar objects as it passes through a stream. With the abilities of Rubin and other observatories, we should be able to identify ISOs that are “siblings,” having originated from the same star system. Over time, this could give us a better idea of the composition and diversity of planetary systems. We may even be able to pinpoint the origin of sibling ISOs to a particular star. One final interesting aspect of these interstellar streams is their overall appearance. Several of the authors of this work are from Aotearoa New Zealand, and they noticed that the simulated patterns have a braided appearance similar to the braided rivers such as Rakaia on the South Island. So they named these interstellar streams he awa whiria, which means the braiding rivers in te reo M?ori, as an homage to that region and its people. It’s a nice reminder of our humanity and the connection between the world around us and the sky above.

A star-studded lineup. Today, the full list of performers for CBS Network's New Year's Eve Live: Nashville's Big Bash was announced, which includes Eric Church, Miranda Lambert, Post Malone, Luke Combs, Chris Stapleton, Zach Top, Lainey Wilson, Jelly Roll, Keith Urban, Kane Brown, Big & Rich, Luke Bryan, Tyler Hubbard, Shaboozey, Brittney Spencer and Parker McCollum. Keith Urban, Kane Brown and Jelly Roll are headlining from Bicentennial Park, and Parker McCollum will perform from the Brooklyn Bowl. Keith Urban and Entertainment Tonight host Rachel Smith will host the show, and the celebration to ring in the new year will air live on Tuesday, December 31st (8:00-10:00 PM, ET/PT, 10:30 PM-1:30 AM, ET/PT) on the CBS Television Network, in addition to streaming on Paramount+*. The show will be executive produced by Robert Deaton and Mary Hilliard Harrington in partnership with Music City Inc., the foundation of the Nashville Convention & Visitors Corp. The special will be directed by Sandra Restrepo in what will be a five-hour broadcast. Nashville will count down with the East Coast at midnight and keep the party going through midnight Central Time with the city’s renowned Music Note Drop at the Bicentennial Mall stage. Other to-be-announced special guests and artist friends will also perform, and more details will be revealed in the coming weeks. This will also mark a first for superstar Post Malone, who has found himself in the thick of country music after putting out his first-ever country album F-1 Trillion earlier this year, which has been nominated for several Grammy Awards, including Best Country Album, as well as the lead single "I Had Some Help (featuring Morgan Wallen)" being up for both Best Country Duo/Group Performance and Best Country Song. Post will set out on the biggest tour he's ever done in support of that album next summer, where he'll play stadiums across the country along with Jelly Roll and Sierra Ferrell for his Big Ass Stadium Tour. You can check out the full list of tour dates below.
