If you can find your way to somewhere with dark skies, you may still be able to catch some of the brighter ones the meteor shower will peak around july 29th. The meteors are most likely to be visible. Starting at 2 am peaking around 3 30 a.m. You can expect around 25 meteors per hour to stay up to date with latest top stories, make sure to subscribe to this youtube channel by clicking the button above this video to find the meteor shower, look south towards the constellation aquarius. If you don’t know where to find aquarius look for jupiter, the planet will be near the constellation all month. Several summer constellations are currently visible at sunset, the constellation hercules and to the south just below ursa minor. If you have a clear view of the southern horizon, you may be able to catch a view of sagittarius. The teapot off to the east you’ll be able to spot cygnus, often called the summer cross to the north. You’Ll see cassiopeia. Her throne shaped like a w on the sky. Can clouds be made out of quartz in space? They can? Dr ben birningham and collaborators recently published a paper studying the composition of clouds in the skies of a nearby brown dwarf, which can be thought of as both a failed star and a super planet. Studying the atmospheres of brown dwarfs helps us understand how exoplanets form and evolve using observations collected from previous studies. They created computer models to try and recreate the compositions of the clouds, depending on the makeup of the cloud.

The light is blocked at different wavelengths. This allows models to try out clouds made of different materials to find which one fits. What we see from their models, dr birningham and his collaborators identified three specific substances primarily responsible for blocking the light iron quartz and ensite. They found the clouds are made up of materials in different quantities than what we see in our solar system. This is exciting as many exoplanet formation models assume clouds will be compassed. Similarly to our solar system, dr birningham’s results show. This is not necessarily the case and more varied models are needed. Do adolescent stars act up frequently, yes, and when they act up, they get brighter. Dr jean guo and his collaborators have published a study. Looking at several of these flaring pre stars, young stellar objects called eso’s are not quite stars. They are collecting materials from their surroundings and have yet to get large enough to start fusing hydrogen like mature stars. Do the material collects in a disk spinning around the star over time the accretion stream could suddenly enhance, which allows a significant amount of surrounding material to fall onto its surface. As this happens, the eso’s, brightness and activity can vary getting somewhat 10 to 100 times brighter. When material falls in and then dimming again, this cyclical, brightening and dimming can take place over a span of months to several decades. Dr guo and his collaborators have identified 33 eso’s towards the galactic center, which all appear highly variable.

By investigating this variability, they can learn what is controlling the star’s growth. They found several of the eso’s disks and thus variability is controlled by the magnetic field of the eso.
