  • Did Asteroids Invent Gum Billions of Years Ago?
    2025-12-06
    What is “gum”? Most people have probably never considered this question, and might answer something like a chewy material you can put in your mouth. But, to a scientist they might answer something like “nitrogen-rich polymeric sheets”, because precisely defining the chemistry of a material is important to them. Or ...
  • SPHERE Shows Us How Our Solar System Isn't Much Different Than Others
    2025-12-05
    Observations with the SPHERE instrument on the European Southern Observatory's VLT revealed the presence of debris rings similar to structures in our Solar System. SPHERE found rings similar to the Kuiper Belt and the Main Asteroid Belt. Though individual asteroids and comets can't be imaged, these debris rings infer that ...

A new piece of analysis by a team led by Seyed Sina Seyedpour Layalestani from the Islamic Azad ...
  • Asteroid loaded with amino acids offers new clues about the origin of life on Earth
    2025-11-29
    One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of life—were transported here by asteroids or other celestial bodies. While these molecules have been found in ...
  • Meteorite samples are time capsules from the early solar system
    2025-11-27
    When a meteor streaks across the sky, it's not just beautiful. It's nature's way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our own, formed.

GADA METEORĪTS
2025
Meteoriti.LV vietne tiks pakāpeniski papildināta ar plašu pamatinformāciju par meteorītiku un ar to saistitām astronomijas nozarēm. Uzzināsiet, vai "meteorīti dabā sastopami retāk par dimantiem", cik tie ir veci un kāda ir to izcelsme. Atradīsiet atbildes uz jautājumiem: Vai meteorīti ir bīstami? Kādi meteorīti atrodami Latvijā un kur tos var apskatīt? Vai Latvijā ir vērts meklēt meteorītus? Ko meteorītu izpēte pastāsta mums par Zemes un Saules sistēmas izcelšanos? Ceram, ka tas radīs vēlmi arī jums pašiem novērot Zemes kosmiskos viesus - meteorus, un, varbūt, pat kļūt par īstiem meteorītu medniekiem!
Veiksmīgu novērošanu!
