Dazzling Auroras possible as geomagnetic storms likely to hit earth

NOAA's Space Weather Prediction Center issued a geomagnetic storm warning for July 30 to August 1 after intense solar activity. Auroras could be visible in mid-latitudes. This warning stemmed from multiple M-class solar flares and CMEs, suggesting potential G3 conditions. Periods of G2 are also anticipated. The first CME impacted Earth's magnetic field on July 29, initiating a minor storm.

Exploring Nasa's latest exoplanet marvels: 6 fascinating discoveries unveiled

On Aug. 24, 2023, more than three decades after the first confirmation of planets beyond our own solar system, scientists announced the discovery of six new exoplanets, stretching that number to 5,502. From zero exoplanet confirmations to over 5,500 in just a few decades, this new milestone marks another major step in the journey to understand the worlds beyond our solar system.The DiscoveryWith the discovery of six new exoplanets, scientists have tipped the scales and surpassed 5,500 exoplanets found (there are now 5,502 known exoplanets, to be exact).Just about 31 years ago, in 1992, the first exoplanets were confirmed when scientists detected twin planets Poltergeist and Phobetor orbiting the pulsar PSR B1257+12. In March 2022, just last year, scientists celebrated passing 5,000 exoplanets discovered.Key Facts Scientists have discovered six new exoplanets — HD 36384 b, TOI-198 b, TOI-2095 b, TOI-2095 c, TOI-4860 b, and MWC 758 c — this has pushed the total number of confirmed exoplanets discovered to 5,502.

Why narcissists are very attractive in the beginning

However, this initial charm fades as relationships progress. Campbell and Stacy Campbell's model of narcissism divides interactions into the "emerging zone" (initial, short-term contexts) and the "enduring zone" (long-term, continuing relationships). In the enduring zone, narcissists exhibit negative behaviors like arrogance and aggression, leading to a decline in their popularity. Narcissists tend to return to the emerging zone to seek the positive social feedback and emotional rush they crave, thus being adept at gaining new friends and social status but poor at maintaining meaningful relationships.

How often do asteroids come near Earth and should we be worried?

The solar system contains at least 1.4 million known asteroids, primarily within the asteroid belt between Mars and Jupiter. Near Earth Objects (NEOs) pose potential collision risks. Daily, Earth encounters over ten tons of dust, while larger objects sporadically strike, causing varying impacts. Notably, the 300-meter asteroid Apophis will pass close in 2029, 2036, and 2068, with low collision risk. Nasa's DART mission showcases asteroid deflection capabilities. No known large asteroid is predicted to hit Earth in the next 1,000 years.
