The Indus River, also called the Sindhū River, or Abāsīn, is a major south-flowing river in South Asia. The total length of the river is 3,180 km (1,980 mi) which makes it one of longest rivers in Asia. It flows through Pakistan, the Indian state of Jammu and Kashmir and western Tibet. Originating in the Tibetan Plateau in the vicinity of Lake Mansarovar, the river runs a course through the Ladakh region of Jammu and Kashmir, towards Gilgit-Baltistan and then flows in a southerly direction along the entire length of Punjab, Pakistan to merge into the Arabian Sea near the port city of Karachi in Sindh. It is the longest river of Pakistan.

The river has a total drainage area exceeding 1,165,000 km² (450,000 sq mi). Its estimated annual flow stands at around 207 km³ (50 cu mi), making it the twenty-first largest river in the world in terms of annual flow. The Zanskar is its left bank tributary in Ladakh. In the plains, its left bank tributary is the Chenab which itself has four major tributaries, namely, the Jhelum, the Ravi, the Beas and the Sutlej. Its principal right bank tributaries are the Shyok, the Gilgit, the Kabul, the Gomal and the Kurram. Beginning in a mountain spring and fed with glaciers and rivers in the Himalayas, the river supports ecosystems of temperate forests, plains and arid countryside.

Indus is a constellation in the southern sky created in the late sixteenth century.

Notable features

Indus does not contain any bright stars. Alpha Indi is the brightest star in Indus. It is an orange giant of magnitude 3.1, 101 light-years from Earth. Beta Indi is an orange giant of magnitude 3.7, 600 light-years from Earth. Delta Indi is a white star of magnitude 4.4, 185 light-years from Earth.

Epsilon Indi is one of the closest stars to Earth, approximately 11.8 light years away. It is an orange dwarf of magnitude 4.7, meaning that the yellow dwarf Sun is slightly hotter and larger. The system has been discovered to contain a pair of binary brown dwarfs, and has long been a prime candidate in SETI studies.

Indus is home to one bright binary star. Theta Indi is a binary star divisible in small amateur telescopes, 97 light-years from Earth. Its primary is a white star of magnitude 4.5 and its secondary is a white star of magnitude 7.0.

T Indi is the only bright variable star in Indus. It is a semi-regular, deeply coloured red giant with a period of 11 months, 1900 light-years from Earth. Its minimum magnitude is 7 and its maximum magnitude is 5.

The modern constellation Indus is not included in the Three Enclosures and Twenty-Eight Mansions system of traditional Chinese uranography because its stars are too far south for observers in China to know about them prior to the introduction of Western star charts. Based on the work of Xu Guangqi and the German Jesuit missionary Johann Adam Schall von Bell in the late Ming Dynasty, this constellation has been classified as one of the 23 Southern Asterisms (近南極星區, Jìnnánjíxīngōu) under the name Persia (波斯, Bōsī).

The name of the western constellation in modern Chinese is 印第安座 (yìn dì ān zuò), meaning "the Indian constellation".

Indus-2 is a synchrotron radiation source with a nominal electron energy of 2.5 GeV and a critical wavelength of about 1.98 angstroms. It is one of the most important projects in progress at the Raja Ramanna Centre for Advanced Technology. It is designed to cater to the needs of X-ray users, material scientists and researchers. Indus-1 has the distinction of being the first synchrotron generator of India with a 450 Mev storage ring. Indus-2 is an improvement over Indus-1.

Indus-2 lattice has been designed in such a way as to give low beam emittance and high brightness. The lattice is a Double Bend Acromat with zero dispersion function along the long straight section. It has eight super periods each having two dipole bending magnets, four focusing and five defocusing quadrupoles and six sextupoles. Of the eight long straight section, three will be used for injection and RF cavities respectively. The remaining five will be used for insertion devices.

The radiation source Indus-2 is in an advanced stage of construction near Indore, Madhya Pradesh.
