A study led by UCLA researchers has revealed that global atmospheric dust microscopic airborne particles from desert dust storms has a slight overall cooling effect on the planet. This phenomenon is thought to have masked the full amount of warming caused by greenhouse gases. Because of this, if dust levels stop climbing, there is potential for climate change to slightly increase in speed.
The research, Mineral dust aerosol impacts on global climate and climate change, published in the journal Nature Reviews Earth and Environment, found that the amount of desert dust has grown roughly 55% since the mid-1800s, which increased the dusts cooling effect.
Researchers at the University of Canterbury, New Zealand, have performed a review titled ‘Envisioning a sustainable future for space launches: a review of current research and policy,’ which analyses the impacts that future rocket launches pose to Earth’s protective ozone layer.
The team hopes their findings will inspire companies and nations to develop sustainable strategies for future endeavours into the final frontier.
Our solar system appears to be in order, with the smaller rocky planets Venus, Earth, and Mars orbiting close to the Sun. On the other hand, the large gas and ice giants, such as Jupiter, Saturn, and Neptune, move in wide orbits around our star. Researchers from the universities of Bern and Geneva, and the National Centre of Competence in Research (NCCR) PlanetS have now revealed that, in this respect, our planetary system may be quite unique.
The findings were published in the journal Astronomy & Astrophysics.
No matter what, you do not want to find yourself near a neutron star.
These stellar beasts, made mostly of neutrons, are basically ultra-dense cosmic corpses roaming around space and, with incomprehensibly strong gravitational fields, torturing everything in their paths.

Russlands Präsident Wladimir Putin und der belarussische Staatschef Alexander Lukaschenko haben in Moskau über die Zusammenarbeit beider Länder in Wirtschafts- und Sicherheitsfragen gesprochen. Dabei unterstrich Lukaschenko nach russischen Agenturberichten die technologische Kooperation der zwei verbündeten, aber international isolierten Nachbarstaaten. Sie lasse die Sanktionen ins Leere laufen, die wegen des russischen Angriffs auf die Ukraine verhängt worden sind, behauptete er.
Die Länder des Westens hätten Russland und Belarus nicht um ihr Potenzial in der Computertechnologie gebracht, sagte Lukaschenko bei dem Treffen in Putins Residenz Nowo-Ogarjowo. Auch produziere Belarus jetzt schon etwa 1.000 Bauteile für die zivilen russischen Flugzeuge MS-21 und Suchoi Superjet. Sein Land sei mit etwas russischer Hilfe auch in der Lage, Erdkampfflugzeuge herzustellen, sagte Lukaschenko. Solche Maschinen dienen der Unterstützung eigener Infanterie-Einheiten und können gegnerische Ziele am Boden angreifen.
