Ceres, an unassuming-looking object made of ice and rock, lies between Mars and Jupiter in the expanse of the Asteroid Belt. It was first spotted by Sicilian astronomer Giuseppe Piazzi on 1 January 1801. This 965-kilometre diameter ball could just have been considered a dead, grey rock in space. -------. It has been discovered that it was – and possibly still is – an active world that may have had cryovolcanoes of the kind that has pretty much disappeared from Earth.
These planets are not the only bodies discovered in our Solar system
Just one solitary peak made of ice, mud and salts, called Ahuna Mons
But as NASA’s Dawn spacecraft has recently uncovered, Ceres has been hiding a strange secret
That is, if it erupts icy materials like water ice, or methane instead of lava
There are also some other mountains on Ceres such as Liberalia and Yamor
(I) Such an assumption has not yet been tested rigorously for most animal species. (II) Vertebrates are often marked to facilitate the identification of free-ranging individual animals or groups for studies of behaviour, population biology, and physiology. (III) Marked animals provide data for home range use, resource selection, social behaviour, and population estimation. (IV) Markers can be classified into three general categories: mutilations, tags and bands, and radio transmitters. (V) The appropriate marking technique for a study depends on several considerations, including study objectives, target species, marker cost, marker efficacy, and marker effects on the animals.
There are many ways to define ‘time’ at a particular location. Here, on Earth, our usual system is defined by the motion of the Sun in the sky. This means that the local time depends on where you are on Earth and we get around this complication by having many different time zones. Now, we could also define a similar time system based on the motion of the Sun as seen from the Moon. Such a system exists but it is not much more than an interesting exercise in physics. -------. This is called Universal Time, and it is a modern form of Greenwich Mean Time. It is the same everywhere in the Universe.
It is difficult to keep track of time at work due to the workload
There have been several unsuccessful attempts to define a brand-new computing system
So, the time on the Moon can never be the same as the time on Earth
What is more useful, however, is a definition of time that does not vary with location
Therefore, it will never be possible to calculate exactly what time it is on the Moon
Bilim insanları, yetersiz petrol ve gaz kaynaklarına sahip olan ülkelerin, yenilenebilir enerjiye geçmesini öneriyor.
The restricted oil and gas resources in the country forced scientists to propose a rapid shift to renewable energy
Scientists recommend that countries with insufficient oil and gas resources should shift to renewable energy
Considering how little oil and gas resources countries have, scientists recommend a shift to renewable energy.
Due to limited oil and gas resources in the country, scientists strongly recommend a shift to renewable energy.
Since the country has limited oil and gas resources, scientists propose to use more renewable energy.
There are objects that are classified neither as stars nor as planets, called ‘brown dwarfs’. -------. Brown dwarfs accumulate matter in the same way as stars, but fail to attain enough mass to ignite hydrogen fusion. Stars can fuse hydrogen into helium, which can only occur above a certain temperature and pressure. Thus, objects above this threshold are stars. Brown dwarfs initially produce heat by fusing an isotope of hydrogen called deuterium into helium-3, which occurs at lower temperatures and lower masses.
NASA is looking for more information about the planets’ atmosphere
Such information will also explain the processes that shaped the young Milky Way
Researchers originally thought that the system had three planets
Thus, more precise measurements will no longer be needed
This term was first coined by Jill Tarter of the SETI Institute
Bazı tasarımcılar için üretim sürecinde yapıtları üzerinde belli bir ölçüde denetime sahip olmaları önemlidir
It is important for some designers to retain a degree of control over their work in the production process
Retaining a degree of control over their work in the production stage is considered vital by designers
For designers who produce certain works, it is necessary to retain a degree of control over their work.
Some designers believe that retaining control over their work in the production process is vital.
According to designers, retaining some degree of control over the production process is really important
High-altitude landscapes are some of the most inhospitable places on Earth. They are cold, dry, and oxygen-poor, which causes sleeplessness, fatigue, coughing, confusion, and a rapid pulse. They were the last places humans settled, yet people did it and survived. -------. From the Himalayas to the Andes to the Ethiopian Plateau, people have evolved in ways that allow them to live at high altitude.
The only logical explanation for this is our ability to adapt, especially to extreme environments
Living at such heights causes hypoxia, a condition where tissues cannot get enough oxygen
The Himalayas and the Andes attract many climbers looking for adventure
This was all about our failure to cope with such an extreme phenomenon
It is easier to find well-protected remains of ancient empires than ever before due to technology
Late in the twentieth century, evidence of global warming mounted as ice sheets in the Arctic and Antarctic began melting rapidly. Carbon dioxide levels climbed, and the protective ozone layer shrank. Although Earth had experienced cycles of abnormal warmth and cold even before humans appeared, most scientists and some political leaders feared that human activity was seriously disrupting the world’s climate. They urged energy conservation and alternatives to carbon-rich oil and coal, such as solar and wind power, hydrogen, and synthetic fuels. -------
However, one of the major challenges facing developing countries today is to find sufficient oil resources
As a result, 140 nations approved an environmental agreement in 2005, known as the Kyoto Protocols, in order to limit destructive emissions
It has been long known that electric utilities using fossil fuels produce greater air pollution than nuclear power plants
Like many developed countries, the United States, proportionally the world’s largest energy user, supports cost-efficient projects
When the cold war was over, many nations started scientific space exploration to discover habitable planet
Dünyanın başka hiçbir yerinde bulunmayan sayısız türün evi olarak bilinen tropik yağmur ormanları, daha önce hiç görülmemiş bir hızda yok ediliyor.
Known to be the home of numerous species found nowhere else in the world, tropical rainforests are destroyed at an unprecedented rate.
Tropical rainforests, which are the home of numerous species existing nowhere else in the world, are being saved at an unprecedented rate.
Although it is known to be the home of numerous species rarely found in the world, tropical rainforests are destroyed at an alarming rate.
Tropical rainforests are the home to numerous species found nowhere else in the world, but they are being destroyed rapidly.
As tropical rainforests are being destroyed at an alarming rate, numerous species found nowhere else in the world are becoming extinct at an unprecedented rate
As honeybees develop, they undergo metamorphosis. -------. At the right moment, the protective wax caps put in place by worker bees are removed, revealing the pupae just days before they are ready to emerge as fully grown adults. Bees in this stage are pale, as their outer shells are not yet hardened. When they emerge as adults, their shells can still take a few hours to fully harden. This means that very young bees are more or less unable to sting
It is a great idea to mark honeybees if you want to follow them
The shell of a new born bee is not as hard as it is supposed to be
Their lifecycle consists of four stages: egg, larva, pupa, and adult
The queen bee is not involved in the process of wax cell production
Young bees, compared to fully grown adults, are less dangerous to us
