Bubbles in glacial ice are a proxy that can be used to recreate past variations in atmospheric carbon dioxide concentrations.
Although they may appear serene and beautiful, glaciers can create a lot of noise when they begin to melt. According to a recent study, as a glacier's ice melts, compressed old air bubbles escape into the water, creating noise levels that are even higher than those found in rain-lashed seas with 6-meter waves. The noise is present year-round and is loudest between 1 and 3 kilohertz, or roughly the pitches in the piano's two uppermost octaves, according to data collected by underwater sensors at three locations where glaciers meet the sea . The researchers published their findings online this week in Geophysical Research Letters.

What is a frequent reason for a stock split?
The board of a firm may elect to divide shares of stock if the share price of the company rises to a level that some investors may find unsettling or surpasses that of other, comparable companies in the same industry.
When a business issues more shares to increase the stock's liquidity, the result is a stock split. The total monetary worth of all outstanding shares remains same even when the number of shares outstanding grows by a specific multiple since a split does not fundamentally alter the company's value. Reverse stock splits are the opposite occurrence, where a corporation decreases the number of shares outstanding as opposed to increasing them, driving up the share price in the process.

given this concept, order the galaxies from most edge-on to most face-on. assume that all of the galaxies are perfectly round and that any apparent elongation is due purely to their orientation.
Galaxy forms are statistically aligned, not arbitrarily orientated, and this alignment can vary depending on the circumstances surrounding galaxy formation, its past, and its current state.
Therefore, studying galactic alignments can provide crucial insights into the astrophysics of galaxy creation, evolution, and the development of structure in the Universe. We summarize the most important intrinsic alignment metrics in this review study, broken down by galaxy type, scale, and environment. Additionally, we discuss the formalism and statistics required to comprehend the observations in the literature. Galaxy alignments have gained in significance as a result of weak gravitational lensing's development as a precise cosmology probe because they can imitate cosmic shear, the impact of gravitational lensing by large-scale structure on observable galaxy forms.In weak lensing research, intrinsic alignments become a significant systematic influence as a result. We estimate the influence of intrinsic alignments on cosmic shear surveys before evaluating realistic mitigation strategies designed to reduce intrinsic alignment contamination.

Felsic minerals are a type of silicate minerals that are light in color and have high levels of silica and aluminum. They are typically made up of quartz, feldspars, and mica, and are usually associated with igneous rocks. Felsic minerals are also known for having low densities and low magnetic susceptibilities. These minerals tend to form during cooling of magma, and are indicative of a granitic or felsic composition in the source rock.

What is weathering?The breakdown or dissolution of rocks and minerals on the Earth's surface is referred to as weathering.
Agents of weathering include water, ice, acids, salts, plants, animals, and variations in temperature.
After a rock has been fractured, the fragments of rock and mineral are carried away by a process known as erosion.
The effects of weathering and erosion cannot be resisted by any rock on Earth due to its softness.
How susceptible a rock is to weathering is frequently influenced by how long it has been exposed.
Lavas, for example, are less prone to weathering and erosion than rocks that are exposed to elements like wind and water because they are soon buried beneath other rocks.
Weathering is frequently the first process in the formation of soils because it softens rough, jagged rock surfaces.
