Hubble records comet’s spin flip as jets reverse its rotation

NASA’s Hubble Space Telescope tracked comet 41P/Tuttle–Giacobini–Kresák and observed its rotation reverse due to jets of gas and dust, with the spin slowing between 2017 observations and then flipping to a much faster rate (about 14 hours) by December 2017. Scientist David Jewitt explains that uneven jets act like tiny thrusters, reversing the comet’s spin, an unprecedented finding that may signal structural changes or breakup; the results were published in The Astronomical Journal.

Misiorowski to Start as Brewers Unveil 2026 Opening Day Roster

Milwaukee finalized its 26-man Opening Day roster for 2026, with Jacob Misiorowski set to start the season as part of a rotation that includes Chad Patrick, Brandon Sproat, Kyle Harrison, and Brandon Woodruff; Jake Woodford was added via trade and will contribute in relief. The catching pair is William Contreras and Gary Sánchez; infielders are Andrew Vaughn, Jake Bauers, Brice Turang, Joey Ortiz, Luis Rengifo, and David Hamilton; outfielders are Jackson Chourio, Sal Frelick, Garrett Mitchell, Brandon Lockridge, and Christian Yelich. The bullpen features Trevor Megill, Abner Uribe, Aaron Ashby, Ángel Zerpa, Jared Koenig, DL Hall, Grant Anderson, and Jake Woodford. Three players are Opening Day rookies (Misiorowski, Sproat, Anderson); five players start the year on the injured list (Priester, Zastryzny, Akil Baddoo, Steward Berroa, Craig Yoho).

Deep Interior Plume Nudges Mars to Spin Up

Deep Interior Plume Nudges Mars to Spin Up

A study using NASA’s InSight data and Viking observations finds Mars’ day length is shortening very slightly, resulting in a rotation speed-up of about 70 microseconds per year. Researchers propose a deep underground negative mass anomaly beneath the Tharsis region is rising, creating melt pockets and moving heavier material toward the rotation axis, which would speed up the planet’s spin and suggests a more active interior with more internal heat than previously thought.

Rookie Lefty Early Earns No. 3 Spot in Red Sox Openers for 2026

Rookie Lefty Early Earns No. 3 Spot in Red Sox Openers for 2026

Rookie left-hander Connelly Early will open Boston’s 2026 season in the rotation as the No. 3 starter after a standout spring (1.59 ERA) and solid late-2025 big‑league showing. The Sox plan to pair him with Johan Oviedo in the early rotation, with Oviedo serving as a multi‑inning reliever and possible piggyback option behind Ranger Suarez as he builds up. Payton Tolle was optioned to the minors, while Jovani Morán and Danny Coulombe join the bullpen alongside established late‑inning arms Aroldis Chapman and Garrett Whitlock, as the club maps out its bullpen and rotation for April.

Yankees Must Unleash Lagrange Now, Without Repeating Joba’s Limits

Carlos Lagrange’s spring showing signals a limitless ceiling and pushes the Yankees to use him in their win-now plan without the Joba Rules-like restrictions that hampered past pitchers; he could serve as a short-term bullpen option while keeping long-term starter potential, but the team must maintain rotation flexibility and avoid burying him in the minors, ensuring they maximize his outs and overall value without repeating old missteps.

Magnetism Steers Sun‑Like Stars’ Spin Across a Lifetime, Study Says

A high‑resolution magnetohydrodynamic simulation of solar‑type interiors on Japan’s Fugaku supercomputer shows sun‑like stars maintain a solar‑like rotation (equator speeds ahead of the poles) throughout their lifetimes, overturning a 45‑year theory of anti‑solar rotation and highlighting the dominant role of magnetic fields and turbulence; the model reproduces the Sun’s rotation and predicts the magnetic field weakens gradually with age, though direct observations remain challenging.

Blue Jays Bring Back Max Scherzer on Incentive-Laden One-Year Deal

Toronto re-signed Max Scherzer to a one-year, $3 million base with up to $10 million in incentives, adding a 60-day IL move for Anthony Santander to clear a roster spot; the future Hall of Famer returns for a second season with the Jays and is expected to begin 2026 in a six-man rotation after a injury-plagued 2025, with CBT payroll around $319 million.

The Spin Factor: Rotation Drives Element Mixing in Red Giants

Researchers using high-resolution 3D simulations on powerful supercomputers found that stellar rotation greatly enhances the mixing of elements from a star’s core to its surface, explaining observed chemical changes in red giants; rotating stars mix materials over 100 times faster than non-rotating ones, revealing rotation as a key driver of stellar evolution and informing predictions for the Sun’s future.

AI fears spark a trillion-dollar rout in U.S. software stocks

U.S. software and data-services stocks fell for a seventh straight session as investors worried AI advances could disrupt the sector, with the S&P 500 software index down about 4.6% and roughly $1 trillion in market value wiped since January 28; heavyweights like ServiceNow, Salesforce and Microsoft led the declines as investors rotated out of tech into value plays amid rising market volatility.
