It’s a galaxy-eat-galaxy universe out there.
Astronomers used the motion of stars to reconstruct a galactic collision that happened 2 billion years ago at the nearest neighboring large galaxy.
The powerful flare caused a radio blackout over South America.
The Sun sent out a very powerful solar flare in the morning hours of Saturday EST time. NASA’s Solar Dynamic Observatory captured a video of the same.

In 2021, Carbon Robotics unveiled the third-generation of its Autonomous Weeder, a smart farming robot that identifies weeds and then destroys them with high-power lasers. The company now has taken the technology from that robot and built a pull-behind LaserWeeder — and it kills twice as many weeds.
The weedkiller challenge: Weeds compete with plants for space, sunlight, and soil nutrients. They can also make it easier for insect pests to harm crops, so weed control is a top concern for farmers.

The world of spectroscopy has continued to expand throughout history based on the contributions of many brilliant scientists. This month we highlight prominent Black scientists whose innovations have helped shape spectroscopy as we know it today and have created space for others like them to succeed.
The 3D-printed rocket from Relativity Space may make its debut flight this month if all goes to plan, marking the first liquid natural gas booster to reach orbit.
The influx of stars into the galaxy next door to the Milky Way was revealed by intricate patterns in their motion today and reflects a violent event in our galaxy’s past.
To launch another pair of Starlink stacks to orbit this week, SpaceX will break its all-time launch pad turnaround record. The first launch, Starlink Group 5–4, is currently scheduled to lift off at 12:10 AM EST (05:10 UTC) on Sunday, Feb. 12, pending a forecasted 20% chance of acceptable weather.
If the launch target holds, the mission will break the record for both Space Launch Complex 40 (SLC-40) at the Cape Canaveral Space Force Station in Florida and the overall record across all three Falcon 9 launch pads. The second mission, Starlink Group 2–5, is slated to launch at 8:32 AM PST (16:32 UTC) on Wednesday, Feb. 15 from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California.
The CEO of Tesla has made it his mission to colonize the planet Mars in our lifetime.
Elon Musk is known for making wild promises and setting outrageous goals. It’s one of his detractors’ biggest criticisms.
But it is also one of the visionary entrepreneur’s driving forces. He thrives on setting goals that society broadly deems unattainable. He loves nothing more than having his back to the wall, the odds against him.
Science Daily reports that the astronomers found out that the mass of this lone white dwarf is equivalent to 56% of the sun’s weight. It aligns with previous theoretical predictions regarding the white dwarf’s mass, and it also sheds light on persisting theories regarding the evolution of these white dwarfs as a result of usual star evolution. The interesting observation grants further understanding of theories regarding white dwarf composition and structure.
According to the Space Academy, the astronomers made use of the renowned Hubble Space Telescope to gauge this lone white dwarf’s mass. The dwarf is known as LAWD 37.
