What country was the first in space?
Germany launched the first rocket into space. This rocket was the first one that actually could "reach space". China was the first one to launch a rocket, but it exploded in midair, lost power and fell, etc... and was more like fireworks or missiles than rockets.
Of course, even if it reached space, it didn't get so far.
How many cells were in the picture that rober hooke drew?
Rober Hooke's drawing of cork cells depicted numerous tiny cells, which he estimated to be around 30 cells across horizontally. However, the exact number of cells in the picture may vary depending on the image and magnification used.
DNA testing began in the 1980s with the development of techniques such as DNA fingerprinting and polymerase chain reaction (PCR). The first major milestone was the discovery of restriction enzymes that can cut DNA at specific sequences, paving the way for more precise genetic analysis. The utilization of these techniques in forensic investigations and paternity testing helped establish DNA testing as a reliable and widely-used tool for identifying individuals and determining relationships.
The roslin institute was responsible for which famous scientific breakthrough?
The Roslin Institute in Scotland was responsible for the cloning of Dolly the sheep in 1996, the first mammal to be cloned from an adult somatic cell. This breakthrough revolutionized the field of genetics and opened up new possibilities for stem cell research and genetic engineering.
What was the actual size of the earth at 1000000 years ago?
The actual size of the Earth at 1 million years ago would have been very similar to its current size. Over such a short timescale in geological terms, there would not have been any significant change in the Earth's size.
What is the first star you see at night?
its the pole star, it is seen the first and foremost at night.
* Many people might say that Yuri Gagarin is dead but he could still be alive and anyway he will always be alive in all our hearts. After changing human history he can not die. * Gagarin was killed in an aircraft crash while continuing training as a fighter pilot on 27 March 1968.
What is the brightest thing in the night sky?
Blue-white stars are the hottest and brightest stars; Sirius A (and its white dwarf companion Sirius B) is the brightest star in Earth's night sky.
Who was the first person to discover Jupiter?
The invention of the telescope is credited to Hans Lippershey. Crude telescopes and spyglasses may have been created much earlier by Dutch opticians, but Lippershey is believed to be the first to apply for a patent for his design. His telescope was made up of one convex lens and one concave lens.
Galileo Galilei perfected it by using two convex lenses. He constructed his first telescope in 1609. This telescope is called the Galilean telescope or the refracting telescope.
Isaac Newton invented a telescope which used two mirrors. He constructed his first telescope in 1669. His version of the telescope was called the Newtonian telescope or the reflecting telescope.
How does a nebula developes into a solar system?
A nebula develops into a solar system through the process of gravitational collapse. As the nebula contracts due to gravity, it starts to spin and flatten into a spinning disk. Within this disk, the material begins to clump together and form planetesimals, which eventually coalesce to form planets, moons, and other objects in the solar system.
Racing can be traced back to ancient civilizations, where it was used as a test of speed and endurance for horses or other animals. Chariot racing was popular in ancient Greece and Rome, while horse racing dates back to the 12th century in England. Over time, racing evolved into a competitive sport involving various vehicles and animals, with modern motorsports emerging in the early 20th century.
Who discovered the benguela current?
The Benguela Current was named after the town of Benguela in Angola. It was not discovered by one specific individual, but rather by sailors and explorers who observed the unique ocean currents in the region.
What measures the ground motion during an earthquake?
Seismometers are instruments that measure ground motion during an earthquake. They detect the movement of the ground caused by seismic waves passing through the Earth. The data recorded by seismometers can help scientists analyze and characterize earthquakes.
Were stars and galaxies created during the big bang?
Is it possible that ALL of the stars we see no longer exist? No.
SOME of them? Sure. A FEW of the more distant stars could easily have already gone supernova, but the light of the explosion is still on its way here to Earth.
That even applies to some relatively nearby stars. The red supergiant star Betelgeuse, at the shoulder of Orion, is known to be very old for its type, and it will explode in a supernova explosion "Real Soon Now". However, "Real Soon Now" to an astronomer means any time within the next 100 centuries or so, so it probably hasn't happened yet.
But it COULD have exploded 500 years ago - but since it is about 850 light-years away, we wouldn't know it for another 350 years!
If the universe has allready collapsed and sucked away every single star except our sun (why??), then yes, we would not notice until 4 years from now when light stops coming from Alpha Centauri followed by the rest over the years.
What are some minerals with a greasy luster?
Some minerals that exhibit a greasy luster include turquoise, serpentine, and nepheline. These minerals have a sheen that resembles the appearance of grease or oil on their surfaces.
How long does it take to sunrise and sunset in Uranus?
Since Uranus has a 92% tilt on its axis, the sun sets every 42 years. One side of Uranus faces the sun for 42 years while the other side faces darkness at the same time. Then when 42 years go by, this reverses.
When were Jupiter's rings discovered?
Jupiter's faint ring system was discovered in 1979 by the Voyager 1 spacecraft. They were confirmed during the Voyager 2 mission in 1979 as well. These rings are primarily made up of dust and small rocks.
How does Bernoulli's Principle effect weather patterns?
Bernoulli's Principle affects weather patterns by influencing the movement of air masses. Differences in pressure cause air to move from areas of higher pressure to lower pressure, creating winds. This plays a role in the formation of high and low pressure systems, which are responsible for generating weather patterns such as storms and weather fronts.
How bright will the sun look on Jupiter?
The sun is extremely bright because it is a nuclear fusion machine that is constantly "on" and generating lots of energy. Additionally, the earth, from which we view the sun, is not so far away that a great quantity of light can't reach earth from our local star.
Why was Louis Pasteur's work not accepted in the scientific community?
Louis Pasteur's work was initially not accepted in the scientific community because it challenged established beliefs and practices, leading to skepticism and resistance. His germ theory of disease, for example, faced strong opposition from scientists who adhered to the prevailing miasma theory. Over time, though, Pasteur's experiments and evidence gradually won over the scientific community, leading to widespread acceptance of his groundbreaking work.
The first company to build a spaceship was Vought, a subsidiary of Chance Vought Corporation. The spaceship, named Vought VE-7, was built in 1917. The owner-president of the Chance Vought Corporation at that time was Chance Milton Vought.
Where is Jupiter located from the sun in terms and miles?
Jupiter is 778 million km or 484 million miles from the sun. See the related link for more information.
Is Earth the densest planet in your solar system?
No, Earth is not the densest planet in our solar system. Mercury holds that title, with a higher average density due to its large metallic core relative to its size. Earth's density is lower because it has a significant amount of lighter materials in its composition.
When was space vacuum discovered?
The concept of space being a vacuum has been understood for centuries, but it was not until the 17th century, with the work of scientists like Galileo and Torricelli, that the idea of a true vacuum in space began to take shape. The discovery and understanding of the vacuum of space has been an ongoing process and continues to be explored through advancements in technology and scientific research.
How did Edmond Halley predict that Halley's comet was coming back again?
He didn't discover it.
He did some calculations that suggested that a certain comet, seen during his lifetime, and three comets seen many years before, had the same orbit, and therefore were all probably the same comet.
He also predicted that this comet would return in a certain year in the future.
It did and it was named as Halley's comet, in his honour.
