The field of the bright x-ray flare EP250702a as seen by the Einstein Probe.
Last summer, China's Einstein Probe detected an unusually fast, bright x-ray signal.
It might have come from an exotic, previously unseen type of cosmic disaster: a white dwarf star being torn apart & consumed by an intermediate-mass black hole. 🧪🔭

A single NSF–DOE Rubin Observatory image will reveal thousands of changing objects in the night sky, from supernovae and variable stars to active black holes and wandering asteroids. This infographic shows approximately how many of each type of object scientists expect to find in each Rubin image. Credit: NSF–DOE Rubin Observatory/NOIRLab/SLAC/AURA
The sheer volume of data coming from the new Rubin Observatory is staggering. In *one* night it issued 800,000 alerts, indicating something that changed in the sky: a moving asteroid, variable star, supernova, etc.
Rubin will be an astonishing discovery machine. 🔭🧪

Illustrated graphic with the boot-shaped Rubin Observatory atop its site on Cerro Pachón beneath a sparkling night sky and the glowing band of the Milky Way stretching from lower left to upper right. Sprinkled throughout are many "Data alert!" popups, labeled with icons that represent supernovae, asteroids, hungry black holes, and more.
A 3-by-4 grid of grayscale astronomical images zoomed in on single objects. From left to right, the columns are labeled Template, New image, and difference. From top to bottom, the rows are labeled supernova, variable star, active galactic nucleus, and solar system object.
The largest spot-the-difference effort EVER has begun!🚨
On the night of Feb 24, NSF–DOE Rubin Observatory officially released its first ~800,000 public alerts of detected changes in the night sky!🔍
A new era of discovery is here✨ 🔭🧪☄️

Photo of an old sheet of paper, title 'The Analemma Improved by B Donn, Bristol. Published by the Author Jan.1st 1770. Upper part: a half circle grid representing a (celestial) sphere, with a half circle scale in degrees. Lower part: several scales, including a calendar. Lower center: a table with star names and their coordinates.
Here's Benjamin Donn's 'Improved Analemma' (1770, Bristol).
Can be used at any latitude to find the sunrise/sunset times, elevation, solar time, as well as the rising, setting & southing of stars.

An image of the young, Sun-like star HD 61005 and its astrosphere in X-ray and infrared light. It appears as a violet flash of light, flared in the lower half, against black space. A few other violet dots of light are present, representing unrelated celestial bodies in the distance. Credit: X-ray: NASA/CXC/John Hopkins Univ./C.M.

FOR THE FIRST TIME, CHANDRA CAUGHT A YOUNG STAR “BLOWING A BUBBLE” CALLED AN ASTROSPHERE!!
Temnothorax kinomurai, a workerless, parthenogenetic social parasite. (A) Young, gynomorphic, i.e., originally winged, queen of Temnothorax kinomurai (left) attempting to sting a T. makora worker (right). (B) Nest of T. kinomurai containing young, winged gynomorphic and wingless intermorphic queens of T. kinomurai (light brown) and dark brown T. makora host workers.
Temnothorax kinomurai is a newly identified ant species consisting solely of queens - there are no workers or males. These social parasites take over the nests of other ant species and reproduce without mating! 🧪

All sorts of cool, crazy things happening at the heart of a deepening nor'easter.

Winter’s Fury - Nor’easters: Not many winter storms have the potential to bury 100 million people in 1-2 feet of snow in a single day. Nor'easters are notorious for packing big wind and copious amounts of moisture they get from the Atlantic. The heavily populated region between Washington D.C., Philadelphia, New York and Boston, the 'I-95 Corridor', is especially impacted by Nor'easters.
You're likely to hear the term "Nor'easter" in the coming days.
They are notorious for packing strong winds and copious amounts of moisture they get from the Atlantic. The heavily-populated “I-95 Corridor” -- is especially impacted by Nor’easters.

“Observed decreasing of radial velocity is explained as gradual downstream mixing of shocked gas with the circumgalactic medium through turbulent entrainment.”

New evidence from the James Webb Space Telescope confirms that a "runaway" black hole escaped from its host galaxy and left a trail of young stars scattered in its wake! 🧪

“For the first time, we were able to watch these turbulent structures form near the Sun and then follow them as they flowed outward with the solar wind,” Habbal said. “Seeing the same features later in space-based images tells us they remain intact over enormous distances.”
No, because we haven’t spread it off earth beyond our solar system yet. But hopefully yes!
