The Tampa Bay Lightning rallied from an early deficit to defeat the Dallas Stars 4-1 on Sunday, extending their point streak to 13 games. Jake Guentzel and Dominic James each recorded a goal and an assist in the victory at American Airlines Center. Andrei Vasilevskiy made 19 saves to secure his 20th win of the season.
The James Webb Space Telescope has produced the most detailed infrared image yet of the Helix Nebula, showcasing a dying star shedding its outer layers. This close-up reveals glowing knots of gas shaped by stellar winds and highlights the nebula's role in recycling material for new stars and planets. Located 650 light-years away in Aquarius, the nebula offers insights into the potential future of our Sun.

A team using the CHARA Array at Georgia State University has produced high-resolution images of the early stages of two nova explosions detected in 2021. These images, created through near-infrared interferometry, reveal the rapidly evolving conditions right after the blasts. The findings indicate that the novae were not simple single events.
An isolated galaxy in the Local Void, NGC 6789, continues to form new stars despite lacking apparent gas fuel. New deeper images reveal no signs of mergers or gas inflows that could explain the phenomenon. The mystery of its star formation deepens, challenging astronomers' understanding of galactic evolution.

Scientists using the LOFAR radio telescope and ESA's XMM-Newton observatory have detected the first confirmed coronal mass ejection from a star other than the Sun. The eruption, from a red dwarf 130 light-years away, traveled at 2400 km per second and could strip atmospheres from nearby planets. This discovery has significant implications for the habitability of exoplanets around such stars.
NASA's James Webb Space Telescope has captured a stunning infrared image of the Pismis 24 star cluster within the Lobster Nebula, showcasing thousands of sparkling newborn stars. Located about 5,500 light-years away in the constellation Scorpius, this region highlights massive star formation sculpted by intense radiation and winds. The image provides rare insights into the evolution of hot young stars.
